Question 1

8 characteristics of living things

Answer 1

Movement
Respiration
Sensitivity
Growth
Reproduction
Excretion
Nutrition

Question 2

cell theory

Answer 2

that all living cells came from pre existing cells

Question 3

what are eukaryotic cells

Answer 3

other than bacteria.
have a nucleus.
have a mitochondria.

Question 4

what are prokaryotic cells

Answer 4

mostly bacteria.
no nucleus.
simply structured.

Question 5

difference between animal and plant cells

Answer 5

plant called have a cell wall, animal cells do not. plant cells have chloroplast making photosynthesis an oppertunity.

Question 6

nucleus

Answer 6

brain of cell.
holds dna.
controls cell.

Question 7

nucleolus

Answer 7

make ribosomes, needed for protein. found within the nucleus.

Question 8

mitocondria

Answer 8

energy source by converting food into energy (ATP)

Question 9

rough endoplasmic reticulum

Answer 9

assembles and modifies proteins

Question 10

golgi apparatus

Answer 10

modifies, sorts, and packages proteins and lipids from the endoplasmic reticulum

Question 11

ribosomes

Answer 11

create proteins based on cell instruction

Question 12

vesicles

Answer 12

transport or store substances

Question 13

chloroplast

Answer 13

use sunlight to create sugar and oxygen

Question 14

vacuole

Answer 14

holds and stores

Question 15

membrane

Answer 15

barrier and protection of cell

Question 16

purpose of photosynthesis

Answer 16

for plants to make their own food and produce oxygen.

Question 17

process of photosynthesis

Answer 17

sunlight, water and carbon dioxide

Question 18

organelles involved in photosynthesis

Answer 18

chloroplast (solar panel)
stroma (produce sugar)

Question 19

aerobic cellular respiration

Answer 19

energy production

Question 20

process of aerobic cellular respiration

Answer 20

glucose, oxygen -> energy, carbon dioxide, water

Question 21

organelles involved in aerobic respiration

Answer 21

cytoplasm
mitocondria

Question 22

simple diffusion

Answer 22

high crowded area of molecules to low

Question 23

facilitated diffusion

Answer 23

movement of cells with special protein transport

Question 24

what is osmosis

Answer 24

Osmosis is the movement of water through a cell membrane from where there’s more water to where there’s less. It happens naturally without energy.

Question 25

endocytosis

Answer 25

cell takes in substances by wrapping its membrane around them and forming a bubble. This bubble then moves into the cell.

Question 26

exocytosis

Answer 26

Exocytosis is when a cell pushes substances out using a vesicle that merges with the cell membrane.
