BIOLOGY CHAPTER 1

Question 1

MAGNIFICATION

Answer 1

the action of magnifying something or the process of being magnified

Question 2

RESOLUTION

Answer 2

resolution is how clearly you can see something while looking through a microscope

Question 3

ORGANISM

Answer 3

an organism is an individual living thing, multicellular or unicellular. an organism has a body made up of smaller parts that work together

Question 4

NUCLEUS

Answer 4

the central and most important part of a a cell. containing the all the cell’s DNA and memory

Question 5

CYTOPLASM

Answer 5

a gooey, jelly like substance inside the cell

Question 6

CELL MEMBRANE

Answer 6

the tissue surrounding the cytoplasm of a cell

Question 7

MITOCHONDRIA

Answer 7

there are 48 of them in each cell and it is also where respiration happens

Question 8

MRS GREN

Answer 8

MRS GREN is an abbreviation often used to help remember all the necessary features of living organisms: Movement, Respiration, Sensitivity, Growth, Reproduction, Excretion and Nutrition

Question 9

CELL WALL

Answer 9

the tissue of a plant cell that surrounds the cell membrane

Question 10

VACUOLE

Answer 10

a space within the cytoplasm of a plant cell, typically containing fluid that has all the food and nutrients that the cell needs to have to live

Question 11

CHLOROPLAST

Answer 11

a vital piece in a plant cell which contains chlorophyll and in which photosynthesis takes place

Question 12

MICROSCOPE

Answer 12

a instrument used for viewing very small objects, such as mineral samples or animal or plant cells

Question 13

SPECIMEN

Answer 13

an individual animal, plant, piece of a mineral. used as an example of its species or type for scientific study or display

Question 14

SLIDE

Answer 14

a microscope slide is a thin flat piece of glass

Question 15

CELL

Answer 15

the smallest unit of an organism, which is typically microscopic and consists of cytoplasm and a nucleus enclosed in a membrane

Question 16

UNICELLULAR ORGANISMS

Answer 16

unicellular organisms are made of a single cell, unlike multicellular organisms that are made of many cells

Question 17

SPECIALISED CELL

Answer 17

some cells in multicellular organisms are modified to carry out a particular function

Question 18

NERVE CELL ADAPTATIONS

Answer 18

a nerve cell has several adaptations that allows it to carry out its needed functions, for example: they are very long in length in order to send messages to the brain quickly.

Question 19

EGG CELL ADAPTATIONS

Answer 19

a egg cell has many adaptations that allows it to carry out its needed functions, for example: the egg cell has adapted so that when a sperm cell meets the egg cell they fuse to form a zygote.

Question 20

SPERM CELL ADAPTATIONS

Answer 20

a sperm cell has many adaptations that allows it to carry out its needed functions, for example: it has a long tail to help it swim up to the egg cell

Question 21

ROOT HAIR CELL ADAPTATION

Answer 21

a root hair cell has many adaptations that allows it to carry out its needed functions, for example: they have a large surface area to absorb water quicker

Question 22

MULTICELLULAR

Answer 22

multicellular organisms are organisms that consist of more than one cell

Question 23

RED BLOOD CELL ADAPTATIONS

Answer 23

red blood cells have many adaptations that allow them to carry out their needed functions, for example: they are small and flexible so that they can fit through narrow blood vessels.

Question 24

DIFFUSION

Answer 24

diffusion is the movement of gas from a area of high concentration to a area of low concentration until they are equal.

Question 25

RATE OF DIFFUSION

Answer 25

the rate of diffusion depends on how hot the gas is, how much kinetic energy it has and how far away from the source of the smell you are

Question 26

BINARY FISSION

Answer 26

binary fission is the most common form of reproduction in unicellular organisms
