- Algae are photosynthetic organisms.
- Algae can be either unicellular or multicellular organisms.
- Algae lack a well-defined body so structures like roots stems or leaves are absent.
- Algaes are found where there is adequate moisture.
- Reproduction in algae occurs in both asexual and sexual forms.
What characteristic do all algae share? They are autotrophs.
What do all green algae have in common?
Green Algae. Chlorophyta or green algae constitute a division that has the following set of attributes: chloroplasts with no external endoplasmic reticulum thylakoids typically in stacks of two to six chlorophyll-a and -b as photosynthetic pigments true starch and cellulosic walls or scales (Table I).
What characteristics are primarily used to classify algae?
- Algae are unicellular filamentous or multicellular (thallic). …
- Most algae live in aquatic environments. …
- Algae are eukaryotic most are photoautotrophs. …
- The thallus of multicellular algae usually consists of a stipe a holdfast and blades. …
- Algae reproduce asexually by cell division and fragmentation.
What are the characteristics of algae and fungi?
Algae are autotrophs and Fungi are heterotrophs. Algae contain photosynthetic pigments. Fungi are capable of digesting non-living organic material and also absorbs simple nutrients by the fungal hyphae. Due to the presence of different photosynthetic pigments algae have different colors like green red and brown.
What characteristic do euglenoids & algae share? Both can be autotrophic. What do plant-like protists & fungus-like protists have what in common?
Which of these is a distinguishing characteristic of algae in the phylum Euglenophyta?
They are characterized by the possession of a single flagellum the formation of paramylum as a storage product possession of chlorophylls a and b and the absence of sexual reproduction.
What are the characteristics of fungi quizlet?
- Eukaryotic (organelles – microfilaments/tubules)
- Basic unit is hyphae – aseptate/septate.
- Hyphal cell walls composed of chitin and glucan.
- Heterotrophic and osmotrophic.
- produce spore.
- most are non-motile (zoospores)
What are the main characteristics of the algae classified under Kingdom Chromista?
Chromista – The Chromista are a paraphyletic eukaryotic supergroup which may be treated as a separate kingdom or included among the Protista. They include all algae whose chloroplasts contain chlorophylls a and c as well as various colorless forms that are closely related to them.
Are algae unicellular or multicellular?
Algae are morphologically simple chlorophyll-containing organisms that range from microscopic and unicellular (single-celled) to very large and multicellular. The algal body is relatively undifferentiated and there are no true roots or leaves.
What is the morphology of green algae?
Green algae contain the same carotenoids and chlorophyll a and b as land plants whereas other algae have different accessory pigments and types of chlorophyll molecules in addition to chlorophyll a. Both green algae and land plants also store carbohydrates as starch.
The characteristic shared by both algae and seed plants is the presence of chloroplasts. Algae and seed plants both have chloroplasts.
All green algae (Chlorophyta) and plants share a common evolutionary ancestor. They both contain the photosynthetic pigments chlorophyll a and chlorophyll b. The two lineages diverged between 630 million and 510 million years ago.
Which characteristics of algae is unique?
Which organism belongs to the algae category?
algae singular alga members of a group of predominantly aquatic photosynthetic organisms of the kingdom Protista.
Why are algae considered an unnatural taxonomic group?
Algae is an unnatural group meaning they do not form a single evolutionary lineage in which they are related to a common ancestor. Algae includes both prokaryotic cyanobacteria (i.e. blue-green algae) and eukaryotic protists (which are neither plants nor animals!).
What is the similarities between algae and fungi?
Vascular tissues are absent in algae and fungi both. Both have eukaryotic cells. Asexual reproduction by fragmentation occurs in both algae and fungi. Reproductive organs lack a protective covering.
What characteristics do algae and plants have in common?
Plants and algae are both photosynthetic. Both are also considered eukaryotes consisting of cells with specialized components. They both also have the same life cycle called alternation of generations.
How do you describe algae?
Protists have nuclear membranes around their DNA. They also have other membrane-bound organelles. Many protists live in aquatic habitats and most are motile or able to move. Protists have complex life cycles that may include both sexual and asexual reproduction.
Animal-like protists are commonly called protozoa (singular protozoan). Protozoa are mostly single-celled eukaryotes. They have membrane-bound organelles and they commonly show the characteristics usually linked with animals such as mobility and heterotrophy.
Which are characteristics of all protists?
All protists are eukaryotes which means they contain a nucleus and have sorted organelles like plastids and mitochondria. Most protists are unicellular although some are simple multicellular organisms. Protista examples include algae molds protozoa and slimes.
What are the major characteristics of red algae?
- Lack of flagella and centrioles.
- Presence of photosynthetic pigments.
- Found both in marine and freshwater.
- They show biphasic or triphasic life cycle patterns.
- They are a multicellular filament blade structure.
- Stored food is in the form of starch and polymers of galactan sulphate.
Do algae cells have cell walls?
Both are autotrophic and play important roles of primary production (photosynthesis that ultimately provides food for all marine organisms) in oceans. What is one charactersitic that you could distinguish dinoflagellates and diatoms?
Researchers identified four characteristics shared by all fungi: fungi lack chlorophyll the cell walls of fungi contain the carbohydrate chitin (the same tough material a crab shell is made of) fungi are not truly multicellular since the cytoplasm of one fungal cell mingles with the cytoplasm of adjacent cells and …
What are characteristics of all fungi?
- Fungi are eukaryotic non-vascular non-motile and heterotrophic organisms.
- They may be unicellular or filamentous.
- They reproduce by means of spores.
- Fungi exhibit the phenomenon of alternation of generation.
- Fungi lack chlorophyll and hence cannot perform photosynthesis.
Terms in this set (10) The five features common to most fungi are saprophytic feeding extracellular digestion reproduction by spores multicellular makeup (you could say hyphae instead) and cell walls containing chitin. The cells in some hyphae are separated by cell walls. Thus are called septate hypha.
Why are algae considered as indicators of pollution in aquatic ecosystems?
Algae are valuable indicators of ecosystem conditions because they respond quickly both in species composition and densities to a wide range of water conditions due to changes in water chemistry. … ratio often determines which algae genera are dominant present or absent in these nutrient-affected water bodies.
What are the basic classification of algae?
Algae are classified into three classes. They are Chlorophyceae Phaeophyceae and Rhodophyceae.
Are all algae aquatic?
