Plant VocabularyAnther -the part of the stamen that produces and contains the pollen
Petals- the colorful, often bright part of the flower. They attract pollinators
Pistil-this is the female part of the flower. It is made up of the stigma, style and ovary
Sepals-leaf like structures which cover and protect the flower bud before it opens
Stamens-the male part of the flower. It is made up of the filament and the anther. It is the pollen producing part of the plant
Reproduction of flowering plants
• All living things need to produce more of their own kind to replace ones that die.
• Flowering plants reproduce by making seeds.• Before a seed can grow into a new plant, they
have to be fertilized by pollen.• Pollen comes from another plant during a
process called pollination.• Pollination and fertilization take place in the
flower of the plant.
Sexual reproduction in a flower
Flowering plant has four main stages:1. Pollination: when the pollen lands on the flower2. Fertilization: when the pollen and seed meet3. Seed dispersal: when the seed is spread around,
away from the plant that made it4. Germination: when the seed, having reached
the ground, starts to grow into a new plant
What is photosynthesis ?
Photosynthesis is the process which plants absorb light energy from the Sun and convert it into chemical energy.
During photosynthesis, a plant produces sugar that it uses as food.
Most plants, photosynthesis occurs in the leaves.
Cellular Respiration• Is the process of releasing energy by breaking
down food.• Animals and people go through this process.• We breathe in oxygen that plants give us.• We eat the plants (and other food) to get sugar.• Our bodies break down this sugar to release
energy and help produce carbon dioxide.• This carbon dioxide that we breathe out is then
used by plants.

Energy from sun stored in glucose
Energy of glucose released
Carbon dioxide taken in Carbon dioxide given off
Oxygen given off Oxygen taken in
Produces glucose Produces carbon dioxide and water
Goes on only in light Goes on day and night
Occurs only in the presence of chlorophyll
Occurs in all living cells
