Flowers contain more stamen than pistils because
stamen produces pollen grains
Integuments
nucellus
What is the importance of colorful flowers in the propagation of species?
Colorful flowers attract birds and bees. They are able to gather pollen and nectar for food and move to the next colorful flower
Pollen sticks to their
feet
Some bees can only get nectar from specific species of flowers.
★ Ecosystem stability ★ loss of biodiversity ★ food safety
asexual formation of a seed
Apomixis
Importance of Apomixis
Helps in the preservation of good characters over generations of crop plants ○ Helps in the production of hybrid seeds with combination of desirable characters ○ Prevents loss of specific characters from hybrid ○ Helps in the cost-effective and time-efficient production of seed
anabolic process in which plants manufacture their own food via the chloroplast
photosynthesis
occurs when plants use light energy to convert carbon dioxide and water into glucose and oxygen
Photosynthesis
applies to other organisms besides green plants
several prokaryotes such as cyanobacteria, purple bacteria and green sulfur bacteria
materials of photosynthesis
water,carbon dioxide, sunlight, chlorophyll
products of photosynthesis
oxygen, glucose c6h12O6/ carbohydrates
where the energy-storing process of photosynthesis takes place
chloroplasts
produced during photosynthesis ○ used to fuel various cellular activities
glucose
by-product of this physio-chemical process
oxygen
green-coloured pigment contained in each chloroplast
chlorophyll
absorbed by chlorophyll molecules
light energy
enter through the tiny pores of stomata located in the epidermis of leaves
carbon dioxide and oxygen
sugars that are another by-products of photosynthesis
glucose and fructose
