S1 Cells and Reproduction

basic unit of life that makes up living organisms

controls what enters and leaves the cell

supports the plant cell. Is made of cellulose

site of chemical reactions in a cell

where photosynthesis occurs in plant cells

made up of multiple cells

controls the cells activities

process which plants convert light energy into sugar

used to show cell structures more clearly when using a microscope

made up of only one cell

stores cell sap in a plant cell

four bases in DNA - A, T, G and C - that join the two strands

found inside nucleus made up of long strands of DNA

genetic information which controls cell function

used to identify individuals based on their DNA

the shape of a DNA molecule

a piece of DNA with instructions how to make a protein

genes passed on from parents e.g. eye colour.

contains amniotic fluid and protects the developing foetus

produced by white blood cells to fight infections.

entrance to the uterus

type of breastmilk which is rich in antibodies

female gamete which is produced in the ovaries

the nucleus of the male and female gamete fuse together

sex cells containing half the genetic information

where female gamete (egg cells) are produced

where fertilisation takes place

puts sperm in the vagina during sexual intercourse

organ which allows substances to pass between mother and foetus

process where organisms produce offspring

male gamete produced in the testes

carries sperm from testes to penis

where sperm cells are produced

connects foetus to placenta

where foetus develops.

where sperm are placed during sexual intercourse

cell created from fertilisation which has a full set of chromosomes

different versions of a gene

characteristics with a whole range of numbers

characteristics can be placed in distinct groups

characteristic will always show in the individual

random change to the DNA of a cell

characteristic that can be masked (hidden) by a dominant gene

differences between members of a species
