Locomotion

Question 16

DNA

Answer 16

Asexual reproduction

Question 17

Organelles

Answer 17

Little organs

Parts of a cell

Maintain the life processes of the cell

Question 18

Cell membrane

Answer 18

Functions as a protective barrier for the cell

Endocytosis

Exocytosis

In both animal and plant cells

Question 19

Nucleus

Answer 19

Cells command centre

Noticeable in the organelle

Contains the genetic information (DNA)

In both animal cells and plant cells

Question 20

Cytoplasm

Answer 20

A jelly like substance that contains the nutrients required by the cell to carry on the life processes

Organelles are in the cytoplasm

In both animal and plant cells

Question 21

Ribosomes

Answer 21

Produce proteins

Made in nucleolus

Floating in Cytoplasm or attached to Endoplasmic Reticulum

Question 22

Endoplasmic Reticulum

Answer 22

Rough ER has ribosomes attached to it

Smooth ER has no ribosomes attached to it

Where many things are made for the cell

Question 23

Vacuoles and Vesicles

Answer 23

Membrane structures that store nutrients, water & other materials

Plant cells have one very large vacuole taking up most of the space in the cell

Animals have a smaller vacuole and more vacuoles

In both animal and plant cells

Question 24

Golgi Apparatus

Answer 24

Séries of flat disc-shapedsacs that package materials for the cell

Question 25

Mitochondria

Answer 25

Convert chemical energy of sugar into a usable energy molecule called ATP Nicknamed the powerhouse of the cell In both animal and plant cells

Question 26

Chloroplasts

Answer 26

Use photosynthesis to convert light, Carbon dioxide and water into sugar & oxygen Only in plant cells

Question 27

Cell wall

Answer 27

Provides protection and strength Found in plant cells

Question 28

Diffusion

Answer 28

Caused by the random motion of particles Movement through fluids from high concentration to low concentration

Question 29

What affects diffusion

Answer 29

Agitation (stirring) Temperature (diffuse faster in warmer liquids) Size of molecule

Question 30

Permeable

Answer 30

A membrane that let’s all materials cross it

Question 31

Impermeable

Answer 31

A membrane that let’s nothing cross it

Question 32

Semi permeable/Selectively Permeable

Answer 32

A membrane that let’s only certain materials cross it Animal and plant cells are semi permeable

Question 33

Osmosis

Answer 33

The diffusion of water crossing a semi permeable membrane Water moves from and area of high concentration of water to an area of low concentration of water
