Cells

Question 1

What are the seven characteristics of living things

Answer 1

(SCREWNS / SCREW N)Respond to stimuli, made of cells, reproduce, use energy, produce waste, take a nutrients, grow in size

Question 2

What is cell theory (3)

Answer 2

All living things are made out of one or more cells
all new cells come from pre-existing cells
the cell is the basic unit of life

Question 3

What are some differences between prokaryotic and eukaryotic cells (3)

Answer 3

Eucaryotic cells are larger about 10 times as large
eucaryotic cells are more complex (have more organelles)
Eucaryotic cells have nucleus

Question 4

What are viruses

Answer 4

Contains a strand of genetic material (DNA or RNA) surrounded by a protein layer coat
Can infect and reproduce in a host cell
Cannot take a nutrients, use energy, produce waste, reproduce on their own
They need to be inside a cell of another organism to reproduce
viruses are in active before they enter a house and can stay in active for hours days or months

Question 5

What is a virus’ lifecycle (5 points)

Answer 5

Attaches to specific host cell
Hereditary material enters a host cell
hereditary material causes a cell to make viral hereditary material and protein
New viruses form inside the host cell
new viruses are released as the wholesale burst open and is destroyed

Question 6

What are some examples of prokaryotic cells

Answer 6

Bacteria

Question 7

What are some eucaryotic cells

Answer 7

Plant cells, animal cells

Question 8

What are some organelles unique to plant cells

Answer 8

Cell wall, chloroplasts

Question 9

What Organelles are unique to animal cells

Answer 9

Flagellum and Celia

Question 10

What is a cell membrane

Answer 10

Protects the cell and controls the movement of things in and out of the cell

Question 11

What is the cytoplasm

Answer 11

Jelly like fluid in which internal organs float

Question 12

What is the nucleus

Answer 12

The control centre of the cell, controls all activity within the cell

Question 13

What is the endoplasmic reticulum (ER)

Answer 13

Makes and folds protein.

Question 14

What are ribosomes

Answer 14

Proteins are assembled, some exist in the cytoplasm while others are attached to the ER

Question 15

What is the Golgi apparatus

Answer 15

Modifies, prepares, and packages proteins in the vesicles

Question 16

What are vacuoles

Answer 16

Balloon like space in the cytoplasm that stores waste and substances not in use right away

Question 17

What are vesicles

Answer 17

Small sacs that transports materials to enter and leave the cell

Question 18

What is the mitochondria

Answer 18

The powerhouse of the cell, Releases energy from food to power to the cell

Question 19

What is the lysosome

Answer 19

Constraints enzymes, stores and provides nutrients, Digest worn out cells

Question 20

What is the cell wall

Answer 20

The cell wall is thick, tough, and provides protection and structure

Question 21

What is chloroplast

Answer 21

Constraints of chemical called chlorophyll, plants make their own food(sugar), through photosynthesis

Question 22

What is the flagellum

Answer 22

Hair like tail that helps the cell move

Question 23

What is the Cilia

Answer 23

Multiple tiny flagellum’s that work together for movement
