Study Notes
Photosynthesis
- Process by which plants, algae, and some bacteria convert light energy from the sun into chemical energy in the form of organic compounds (glucose)
- Occurs in chloroplasts, organelles found in plant cells
- Requires:
- Light energy from the sun
- Water (H2O)
- Carbon dioxide (CO2)
- Produces:
- Glucose (C6H12O6)
- Oxygen (O2)
Pollination
- Transfer of pollen from the male reproductive organ of a plant (anther) to the female reproductive organ (stigma)
- Allows for fertilization and reproduction
- Agents of pollination:
- Insects (bees, butterflies, moths)
- Birds
- Bats
- Wind
Parts of a Plant
-
Roots:
- Underground structures that absorb water and nutrients from the soil
- Anchor the plant in place
-
Stem:
- Connects the roots to the leaves
- Supports the plant's height and structure
-
Leaves:
- Organs of photosynthesis
- Contain chloroplasts for light-dependent reactions
-
Flowers:
- Reproductive structures that produce seeds
- Contain male (anther) and female (stigma) reproductive organs
-
Seeds:
- Contain the embryo of a new plant
- Protect the embryo with a hard outer coat
Bees
-
Importance in pollination:
- Responsible for pollinating 1/3 of the world's crop species
- Visit flowers in search of nectar and pollen
- Accidentally transfer pollen between flowers, facilitating pollination
-
Bee biology:
- Social insects that live in colonies
- Have a complex communication system based on dance and pheromones
Plant Reproduction
-
Types of reproduction:
- Sexual reproduction: involves the fusion of male and female gametes (pollen and egg cells) to produce seeds
- Asexual reproduction: involves the production of offspring from vegetative parts of a plant (e.g., runners, tubers)
-
Life cycle:
- Seed germination
- Seedling growth
- Maturation and flowering
- Pollination and fertilization
- Seed production and dispersal
Photosynthesis
