Question 10

Prokaryote

Answer 10

Organism classified as belonging to the Prokaryotae kingdom

Question 11

Eukaryotes

Answer 11

member of the group of organisms that has a membrane around the nucleus in each of their cells

Question 12

Cell Membrane

Answer 12

structure that encloses the contents of a cell and allows the movement of some materials in and out

Question 13

Cytosol

Answer 13

The fluid in the cells

Question 14

Ribosomes

Answer 14

Small structures within a cell in which proteins such as enzymes are made

Question 15

Cytoplasm

Answer 15

the jelly-like material inside a cell. It contains many organelles such as the nucleus and vacuoles

Question 16

Metabolism

Answer 16

the chemical reactions occurring within an organism that enable the organism to use energy and grow and repair cells

Question 17

Binary Fission

Answer 17

reproduction by the division of an organism (usually a single cell) into two new organisms

Question 18

Animalia

Answer 18

the kingdom of organisms that have cells with a membrane around the nucleus, but no cell wall, large vacuole or chloroplasts

Question 19

Plantae

Answer 19

the kingdom of organisms that have cells with a membrane around the nucleus, cell wall, large vacuole and chloroplasts, commonly called plants

Question 20

Fungi

Answer 20

the kingdom of organisms, such as mushrooms and moulds, that help to decompose dead or decaying matter

Question 21

Protoctista

Answer 21

the kingdom of organisms, including algae and protozoans, that do not fit into other groups

Question 22

Prokaryote

Answer 22

the kingdom of organisms that consist of single cells with a nucleus not surrounded by a membrane or a cell wall, commonly called bacteria

Question 23

Mitochondria

Answer 23

Small rod-shaped organelles that supply energy to other parts of the cell. They are usually too small to be seen with light microscopes. Singular = mitochondrion.

Question 24

Cellular Respiration

Answer 24

The chemical reaction involving oxygen that moves the energy in glucose into the compound ATP. The body is able to use the energy contained in ATP.

Question 25

Photosynthesis

Answer 25

the food-making process in plants that takes place in chloroplasts within cells. The process uses carbon dioxide, water and energy from the sun.

Question 26

Chlorophyll

Answer 26

The green-coloured chemical in plants that absorbs the light energy used in photosynthesis to make food from carbon dioxide and water

Question 27

Light Microscope

Answer 27

A light microscope can identify and magnify light cells
