Biotic factors are the living parts of an ecosystem

Question 13

eukaryote

Answer 13

A eukaryote is an organism whose cells have a nucleus and other membrane-bound organelles

Question 14

prokaryote

Answer 14

A prokaryote is a single-celled organism that lacks a nucleus and other membrane-bound organelles

Question 15

organelle

Answer 15

An organelle is a part of a cell that has a specific function and is usually enclosed within its own membrane. Organelles are found only in eukaryotic cells, not in prokaryotic cells like bacteria.

Question 16

Mitochondrion

Answer 16

an organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occurs

Question 17

Answer 17

A chloroplast is a cell organelle that produces energy through photosynthesis.

Question 18

nucleus

Answer 18

a dense organelle present in most eukaryotic cells, containing the genetic material.

Question 19

ribosome

Answer 19

A ribosome is a cellular structure that performs protein synthesis

Question 20

Cell membrane

Answer 20

Also known as the plasma membrane, is a double layer of lipids and proteins that surrounds a cell.

Question 21

Cell wall

Answer 21

A cell wall is an outer layer surrounding certain cells that is outside of the cell membrane. The cell wall provides strength and structural support to the cell.

Question 22

Layer of sticky compounds that aid bacteria to stick to food sources.

Answer 22

Layer of sticky compounds that aid bacteria to stick to food sources.

Question 23

hyphae

The one-celled reproductive unit of fungi.

Question 25

endospore

Answer 25

A rounded, inactive form that certain bacteria assume under conditions of extreme temperature, dryness, or lack of food.

Question 26

fermentation

Answer 26

A metabolic process by which organic molecules (normally glucose) are converted into acids, gases, or alcohol in the absence of oxygen

Question 27

virus

Answer 27

A virus is a chain of nucleic acids (DNA or RNA) often housed in a protein coat or protein envelope, a protective covering which allows the virus to survive between hosts.
