Summary Introduction
To answer:
The membranous organelles possessed by the eukaryotic Ostreococcus tauris.
Introduction:
There are different kinds of cells that range from single cell to multi-cellular organisms. Some cells are independent and have the ability to synthesize their own food. Some cells are intracellular

Paramecia live mostly in freshwater and move with the use of structures called cilia. They utilize contractile vacuoles to expel water that enters the cell by osmosis. Euglena are unicellular organisms that use flagella for movement and chloroplasts for photosynthesis. They are found in freshwater and saltwater. Scientists have determined that Paramecia and Euglena are eukaryotes and not prokaryotes because they have
Which of the following prokaryotes has a relatively large surface-to-volume ratio for rapid gas exchange, despite having one of the largest cytoplasmic volumes of any known eubacterial cell?
the archaeobacterium Halobacterium halobium
the archaeobacterium Nanoarchaeum equitans
the eubacterium Rhodopseudomonas viridis
the eubacterium Epulopiscium fishelsoni
the eubacterium Escherichia coli
What are the differences between a free living celled organism such as paramecium and a single human cell such as a cilliates cell of the respiratory tract?

It is a long, thin extracellular (exterior) structure, with a basal motor embedded in the cell membrane/cell wall. It is identical to the archaeal flagellum (archaellum) in composition and structure, but very different in composition and structure from bacterial flagella. It is a long, thin structure containing bundles of microtubules and motor proteins, all within the plasma membrane. Eukaryotic cells do not possess flagella.arrow_forward

State the answer directly, no need to explain. 1. Chlorophyll is the solar energy-capturing organelle derived from photosynthetic bacteria. 2. Proteins embedded on the plasma membrane may also transport some molecules to and outside the cell. 3. Nuclear envelope is a double membrane with pores that separates the nucleus from the rest of the cell. 4. Eukaryotic cells are considered the first cell type on Earth and are the cell type of bacteria and archaea. 5. Cell wall surrounds plasma membrane which is common among plants, fungi and many protists. 6. Ribosomes direct the synthesis of RNA. 7.

- In the diagram below, identify the structures of a cyanobacterial cell based on the following descriptions: a) Outer cellular covering which includes: Mucilaginous layer – outermost layer covering the cell wall; protects the cell from harmful factors of the environment Cell wall – found just below the mucilaginous layer; 2 or 3-layered, the inner layer lies in between the outer wall layer and plasma membrane; the outer layer is made of peptidoglycan Innermost plasma membrane – selectively permeable membrane enclosing the cytoplasm b) Cytoplasm – found below the plasma membrane; the protoplasm which contains structures of different shapes and functions. Lamellae, which contain pigments such as chlorophylls, carotenes, xanthophylls, phycoerythrin and phycocyanin, are located in the peripheral region of cytoplasm.
