Answer:
Cell Wall: This is the rigid outermost layer of a plant cell. It makes the cell stiff -providing the cell with mechanical support - and giving it protection. Animal cells do not have cell walls. Cell Membrane: This is a protective layer that surrounds every cell and separates it from its external environment.
A flower has the following:
Petals - segments of the flower
Sepal - outer parts of the flower at the bottom covered in bud
Stamen - produces pollen in the flower
Anther - where pollen is produced
Pistil - produces ovary of the flower
Stigma - where pollen germinates
Pollination occurs when insects like bees and butterflies transfers the pollen from one flower to another. Once transferred, fertilization begins.
