After completing this lesson, student must be able to:

  • List and describe some microscopic organisms.
  • Draw and list the parts of flowers.
  • Describe the types of seed.
  • Write modification of different parts of plant.
  • Explain the function, dispersion and germination of seed.
  • Define pollination and fertilization in plants.

Notes

Some Microscopic Organisms

Bacteria are microscopic organisms whose single cells have neither membrane-enclosed nucleus nor other membrane-enclosed organelles like mitochondria and chloroplasts.

Modification of Different Parts of Plant

Roots, stem and leaves are main parts of plants. This note provides us an information about modification of different parts of the plant.

Seed

The monocotyledonous seed has only one cotyledon. This note provides us an information about the types of seed.

Function, Dispersion and Germination of Seed

Dispersion is scattering of seed from one place to another. This note provides us an information on function, dispersion and germination of seed.

Flower

The majority of the plants that we see around us, bear flowers and reproduce by seeds. Hence, they are called flowering plants. This note provides us an information on parts of the flower.

Pollination and Fertilization in Plants

The process of transfer of pollen grains from an anther to the stigma of a same or different flower is called pollination. This note provides us an information on pollination and fertilization in plants.
