A researcher discovers a new prokaryote that lives on the seafloor near hydrothermal vents. This organism reduces CO2 to form C6

expeople1 [14]

Answer:

D. Chemoautotrophs

Explanation:

Autotrophs in plain are organisms that synthesize their own food while hetrotrophs are organisms that do not synthesize their own food.

Chemotrophs (Chemoautotrophs and Chemohetrotrophs) are a group of organisms that obtain their energy through the oxidation of inorganic molecules, These organisms require carbon to survive and reproduce.

Chemoautotrophs are able to produce inorganic molecules by the fixation of CO2 from their immediate environment. The energy required for this process is got from Nitrogen, Magnesium, Sulphur etc.

Chemohetrotrophs are a class of chemotrophs that are unable to synthesize their own food but rather ingest complex molecules like carbohydrates from the environment.

Phototrophs are a group of organisms unlike chemotrophs that depend on the source of light or sunlight for synthesizing its food or organic molecules.

Photoautotrophs are basically photosynthetic plants which are able to carry out photosynthesis ie the conversion of CO2 and H2O to give Glucose and Oxygen in the presence of sunlight.

Photohetrotrophs are a class of organisms that do not synthesize their own food but rely on other organisms or already made organic molecules.

Drag and drop the terms at the left to match the appropriate descriptions at the right. ResetHelp Composed of phospholipid bilay

quester [9]

Answer: The appropriate description is matched against the components of the cell below.

1) Cilia: Short, hairlike cellular extensions

2) Ribosome: Site for protein synthesis

3) Chromatid: Copy of a chromosome

4) Cristae: Folds of the inner mitochondrial membrane

5) Lysosomes: Vesicles with powerful digestive enzymes.

6) Smooth ER: Stores calcium ions in muscle cells

7) Plasma membrane: Composed of phospholipid bilayer

8) Cytosol: Intracellular fluid

9) Cytoplasm: Intracellular fluid and organelles

10) Centriole: Involved in mitosis.

Explanation:

A cell is simply defined as the structural and functional unit of an organism. It is made up of highly organized physical structures called intracellular organelles. These organelles includes:

• Ribosome

• Lysosomes

• Smooth Endoplasmic reticulum

• Plasma membrane

A type of cellular motion called ciliary movement, is a whip-like movement of CILIA on the surface of cells takes place in the respiratory airways of human.

The cytoplasm is filled with both intracellular fluid and organelles while the cytosol contains mainly dissolved proteins, electrolyte and glucose ( intracellular fluid).
