Reproduction Flashcards
What is Amniotic fluid
Amniotic fluid I’d the fluid which surrounds the Fetus which pretexts the Fetus from any damage
What is the Anther
The archer is the male part of the flower which produces pollen
What is Asexual production
Asexual production is the production of offspring from one parent
Genetically identical, Disease issue
Lots of offspring
Not a long time
What is the Carpel
The Carpel is a female part of the plant, it contains their stigmas, ovaries and styles
What is a cutting
A cutting is when a piece of a plant is cut from a plant (stem, root or leaf) and grown with plant rooting hormone and other nutrients into a new plant. Artificial asexual reproduction
What is an Embryo
An Embryo is young organism where rapid division of cells is occurring
In plants it develops in the seed
In humans it develops in the stages between Zygote and Fetus
What is the Fetus
The Fetus is the name of a baby developing in the uterus
What is a fruit (biological terminology)
A fruit is the fleshy structure surrounding a seed, formed from the ovary after fertilisation
What is a gamete
A gamete is a cells cell (meiosis devision of cells)
What is the ovary
The ovary is the structure containing immature egg cells
What is an Ovule
An Ovule is the female structure in a flower which contains one egg cell
What is the placenta
The placenta is a structure formed by a Fetus that attaches to the uterus was and exchanges essential substances between the mothers blood and the blood of the Fetus
What is a pollen grain
A pollen grain is a male structure in a plant that contains the male gametes
What is the pollen tube
The pollen tube is a tube that forms for the male gametes to go down, from the stigma to the female gametes I the ovary
What is pollination
Pollination is he process in which pollen from one flower is transferred to another flower
What is a seed
A seed is a hard shelled structure formed from the ovule that contains the plants embryo and food source
What is sexual reproduction
Sexual reproduction is the production of new individuals by the fusion of a male and female gamete
What is the male gamete in humans
Sperm
What is the stamen
The stamen is the male structure which contains the anther
What is the stigma
The stigma is the female structure win flowers which pollen grains attach to in pollination
What is a style
A style is the structure which supports the stigma in the flower, pollen tube grows within
What are the testes
The testes are the site of sperm production in men
What is a Zygote
A Zygote is a fertilised egg, formed from the fusion of a male gamete and female gamete
what are the Phenotypes
Characteristics, E.g. blue eyes, long fingers…
what are the genotypes
the alleles, E.g. Gg or GG…
what are the gametes
sexual cells, E.g. Sperm or Egg
what does the placenta help the baby in the Ovary with
placenta removes waste products, such as carbon dioxide
gives the baby nutrients, such as amino acids and oxygen
what is micropropagation
micropropagation is the cutting of a plant to then place it into the ground after being sterilised and coated in hormones (auxin)
what are the two ways to clone plants
- micropropagation / cutting
- by taking a tissue of the plant and placing it in a agar to grow with the nutrients
