Tissues Cells And Molecular Studies

Question 1

Mitosis

Answer 1

The type of cell division responsible for growth

Question 2

Tissues

Answer 2

Groups of cells of similar structure that perform a particular function. Histology

Question 3

Embryo

Answer 3

Cluster of undifferentiated cells

Question 4

Interphase

Answer 4

Dna replicates and now a chromatid. 46 needed

Question 5

Nucleus

Answer 5

Controls all cells activities
Carries hereditary info
Synthesis of protein

Question 6

Prophase

Answer 6

Chromatids become visible centrioles split

Question 7

Metaphase

Answer 7

Chromatids line up along the equator

Question 8

Anaphase

Answer 8

Chromosome splits and moves apart to opposite sides of the poles

Question 9

Telophase

Answer 9

Chromosomes regroup and at the poles and cell splits in two

Question 10

Cytokinesis

Answer 10

Animal cell equator constricts

Plant cell cell plate forms and cell splits

Question 11

Apoptosis

Answer 11

When a mutant in a cell is detected the cell commits suicide.

Question 12

What makes a cell cancerous

Answer 12

Cells that have undergone mutations in their DNA. The mutation damages apoptosis

Question 13

Carcinogens

Answer 13

Agents capable of causing cancer, the damage DNA so allow for mutations

Question 14

Tumours

Answer 14

Benign surrounded by tissue and can be easily removed

Malignant invade surrounding tissue and real ease cells which can spread cancer throughout the body

Question 15

Biopsy

Answer 15

A sample if the tu our U.S. removed and examined. Typical for malignant tumours

Question 16

Methods of cancer treatment

Answer 16

Surgery-removing capable tissue
Radiotherapy-irreplaceable organs and tissues
Chemotherapy- when location and size if tumour is unknown

Question 17

What is biotechnology

Answer 17

Use of tech to obtain useful products from living organisms

Question 18

Uses if biotechnology

Answer 18

Blood transfusion, vaccines and immunity, anti-biotics, In Vitro fertilization

Question 19

Somatic cell

Answer 19

Contain complete sets of info that makes us us. They are body cells that can be used to clone

Question 20

Why use embryonic cells to make clones

Answer 20

Stem cells have the ability to rapidly divide. Undifferentiated cells with the potential to firm all kinds of tissue

Question 21

What is cloning

Answer 21

The exact replication of an animal using its exact same genes.

Question 22

Meristematic cells

Answer 22

Cells that continuously divide in plants

Question 23

Uses of cloning

Answer 23

High fruit and veg yield

Traditional healers

Question 24

Why clone

Answer 24

Endangered species are saved from extinction
Produce organs for organ transplants
Improve quality and quantity of agricultural products

Question 25

Therapeutic and reproductive cloning

Answer 25

Clones tissues for organs

Creates replicas of individuals

Question 26

Stem cell differences

Answer 26

Adult can only produce tissue of its origin

Embryonic tissue of any kind
