Organisation of the organism

Question 1

Cytoplasm

Answer 1

found inside the cell and contains all the other cell structures

Question 2

The large nucleus is surrounded by a

Answer 2

nuclear membrane to separate it from the
cytoplasm

Question 3

The cell membrane surrounds the

Answer 3

cell

Question 4

The cell wall is made of

Answer 4

cellulose and surrounds the cell membrane in plant cells

Question 5

Chloroplasts

Answer 5

organelles found in the cytoplasm that are packed with the pigment chlorophyll and so are green in colour

Question 6

Vacuoles

Answer 6

are large vesicles that take up a large part of the interior of plant cell

Question 7

Mitochondria

Answer 7

singular: mitochondrion) are organelles found throughout the cytoplasm

Question 8

Ribosome

Answer 8

are tiny structures that can be free within the cytoplasm or attached to a system of membranes within the cell known as Endoplasmic Reticulum

Question 9

Endoplasmic reticulum

Answer 9

studded with ribosomes looks rough under the microscope; this gives rise to its name of Rough Endoplasmic Reticulum
(R.E.R.)

Question 10

Vesicles

Answer 10

also be seen using a higher magnification – these are small
circular structures found moving throughout the cytoplasm

Question 11

Nucleus function

Answer 11

Contains genetic material in chromosomes which
Control how cells grow and work
Controls cell division

Question 12

Cytoplasm function

Answer 12

supports cell structures
site of many chemical reactions
contains water and many solute

Question 13

Cell membrane function

Answer 13

holds the cell together
controls substances entering and leaving the cell

Question 14

Cell wall function

Answer 14

gives the cell extra support and defines its shape

Question 15

Chloroplast function

Answer 15

site of photosynthesis, providing food for plants
the chlorophyll pigments absorb light energy needed for the reaction to
occur

Question 16

Vacuoles function

Answer 16

contains cell sap
used for storage of certain materials
also helps support the shape of the cell

Question 17

Mitochondria function

Answer 17

site of aerobic respiration, providing energy for the cell
cells with high rates of metabolism (carrying out many different cell reactions) will have significantly higher numbers of mitochondria than cells with lower numbers of reactions taking place in them

Question 18

Ribosomes function

Answer 18

site of protein production in protein synthesis

Question 19

Vesicles function

Answer 19

used to safely transport substances from one part of the cell to another

Question 20

New cells are produced by

Answer 20

division of existing cells.

Question 21

Specialized cells have

Answer 21

specific functions

Question 22

ciliated cells

Answer 22

movement of mucus in the trachea and bronchi

Question 23

root hair cells

Answer 23

absorption

Question 24

palisade mesophyll cells

Answer 24

photosynthesis

Question 25

neurons

Answer 25

conduction of electrical impulses

Question 26

red blood cells

Answer 26

transport of oxygen

Question 27

sperm and egg cells (gametes)

Answer 27

reproduction

Question 28

sperm and egg cells (gametes)

Answer 28

reproduction

Question 29

Magnification =

Answer 29

image size/ actual size

Question 30

1mm =

Answer 30

1000μm
