Biology Interphase And Metaphase

Question 1

What is cytokinesis?

Answer 1

The act of the cell physically splitting in two

Question 2

What happens during telophase?

Answer 2

The spindle fibres start to disapear. Then the nuclear membrane and the nucleons reappears at each part of the cell. The chromosomes begin to uncool and become threadlike again

Question 3

What happens during anaphase?

Answer 3

The proteins holding the chromatids together at the centromere break apart

The separated chromatids now called daughter chromosomes are pulled apart by spindle fibres.

The spindle fibres now pull the separated daughter chromosomes to opposite sides of the cell.

Question 4

What happens during metaphase?

Answer 4

The centrioles reach opposite ends of the cell.

Each centromere becomes attached to two spindle fibres one from each centriole.

The chromosomes are moved by the spindle fibres so that they line up at the middle of the cell

Question 5

What is the longest phase of mitosis?

Answer 5

Metaphase!

Question 6

What happens in late prophase?

Answer 6

The nuclear structures and nuclear membrane disintegrate

The miotic spindle fibres attach to the chromosomes or their centromeres

Question 7

What happens during early prophase?

Answer 7

The chromatin (DNA and Protein) that makeup the chromosomes condensed

Two organelles called centrioles migrate to opposite ends of the cell

Tread like tubules called miotic spindle fibres extend from the centrioles

Question 8

What phase is prophase in mitosis? (Example first second third fourth)

Answer 8

It’s the first phase of mitosis

Question 9

What are the four phases in mitosis?

Answer 9

Prophase

Metaphase

Anaphase

Telophase

Question 10

What happens in animal cells during cytokinesis?

Answer 10

The cel membrane pinches froward eventually splitting the one cell into two cels

Question 11

What is the purpose of mitosis?

Answer 11

Is to provide new cells in multicellular organisms or for reproduction in single cells organisms

Question 12

What is cell division?

Answer 12

Is the process by which a single cell divides into two identical daughter cells

Question 13

What happens in plant cells during cytokinesis?

Answer 13

The cel plate forms the cell wall and the inner cell membrane in each of the new cells

Question 14

What is cytokinesis?

Answer 14

The process that a cell uses to split the cytoplasm in two forming two daughter cells

Question 15

What is mitosis?

Answer 15

The process that a cell uses to split the nucleus in two, making sure that each daughter cell gets a complete copy of DNA

Question 16

How many parts are in M-phase

Answer 16

2 parts

Mitosis and cytokinesis

Question 17

What is another name for M-phase?

Answer 17

Cell division

Question 18

What happens during S-phase?

Answer 18

The cell replicates it’s DNA during the sphase so that each cell will have a copy after mitosis

Question 19

How many phases does the cell go through of growth and preparation

Answer 19

Two periods of growth and preparation

G1 and G2

Question 20

As the cell gets bigger, the cytoplasm increases faster than the surface area of a cells membrane, what problems does this cause?

Answer 20

This makes it harder for the cell to absorb substances and expel wastes

Question 21

What happens to the cel as it gets bigger in this phase?

Answer 21

The volume of a cells cytoplasm increases faster than the surface area of a cels membrane

Question 22

What happens during interphase?

Answer 22

The cell fakes in nutrients grows and conducts other normal cells functions

Question 23

How much time does a cell spend in interphase?

Answer 23

About 90%
