Which phylum contains the organisms responsible for most of the photosynthesis that occurs on Earth?
Phylum Chrysophyta contains the diatoms, which are responsible for most of the world's photosynthesis.
What are large deposits of diatom remains called?
What are large deposits of diatom remains called? List two uses of these deposits. They are called diatomaceous earth. Two uses include being used as an abrasive and to kill insects.
What is the difference between the conjugation that occurs between paramecia and the conjugation that occurs between bacteria?
What is the difference between the conjugation that occurs between paramecia and the conjugation that occurs between bacteria? In conjugation between paramecia, they simply exchange DNA. Bacterium conjugation happens when the bacterium takes the others DNA. Two microorganisms groups are studied.
What is the function of a contractile vacuole What is the difference between this and a food vacuole?
What is the difference between this and a food vacuole? A contractile vacuole collects excess water and releases it into the cell's surroundings. It regulates the amount of water in the cell, while the food vacuoles store and hold food.
What is unique about the euglena?
The Euglena is unique in that it is both heterotrophic (must consume food) and autotrophic (can make its own food). Chloroplasts within the euglena trap sunlight that is used for photosynthesis and can be seen as several rod-like structures throughout the cell.
What is the difference between a macro and a micro nucleus quizlet?
The macronucleus is the larger of the two types of nuclei in ciliate protozoans. It controls all cell functions except reproduction. The micronucleus is smaller and controls the reproductive functions.
What single feature could be used to separate the different phyla of algae?
Within the classification of algae, individual species are divided into five groups, based on characteristics such as type of chlorophyll molecule used in photosynthesis and type of reproductive cycle.
Why do ciliates have two nuclei?
11. Why do ciliates have two nuclei (pl. ... Ciliates requires so much energy that they must have a nucleus (called the macronucleus) devoted solely to metabolism. The other, smaller nucleus (the micronucleus) controls reproduction.
How do paramecia obtain new genetic material through conjugation?
As in bacteria, conjugation in Paramecium involves cell-to-cell contact and transfer of genetic material. However, conjugation in Paramecium involves first meiotic and mitotic divisions of its diploid germinal set of chromosomes, followed by bidirectional exchange of an entire haploid nuclei between conjugating cells.
What are the main features that separate organisms into phylum Protozoa?
Introduction. Essentially, protozoa are single-celled eukaryotes. This means that they are single celled organisms that have a nuclei as well as a number of other important organelles within the cytoplasm and enclosed by a membrane. They exist as free-living organisms or as parasites.
What is the difference between Endoplasm and ectoplasm?
Endoplasm generally refers to the inner (often granulated), dense part of a cell's cytoplasm. This is opposed to the ectoplasm which is the outer (non-granulated) layer of the cytoplasm, which is typically watery and immediately adjacent to the plasma membrane.
What is the function of a contractile vacuole Why do some protists need these?
The point of the contractile vacuole is to pump water out of the cell through a process called osmoregulation, the regulation of osmotic pressure. It occurs in freshwater protists, but mainly in the kingdom Protista as a whole.
What is the difference between a central vacuole and a contractile vacuole?
When a plant has been without water for a long time, the central vacuoles lose water, the cells lose shape, and the whole leaf wilts. ... Instead, these cells collect the excess water into a contractile vacuole, which, as its name suggests, can contract.
What is the function of contractile vacuoles in aquatic protists?
The point of the contractile vacuole is to pump water out of the cell through a process called osmoregulation, the regulation of osmotic pressure. It occurs in freshwater protists, but mainly in the kingdom Protista as a whole.
