Plant Organs Flashcards
What is the flower part of a plant?
Flowers are specialized structures developed for sexual reproduction.
What kinds of sexual reproductive structures can flowers have?
They contain male or female reproductive structures, or sometimes both
What do the male reproductive structures of plants produce?
Male reproductive structures produce pollen grains.
What is the purpose of characteristics like colourful (large/fragrant flowers and necter) for flowering plants?
These plants often have large, colourful, and fragrant flowers to attract their would-be pollinators. Most also
produce nectar as an added form of attraction.
What do the female reproductive structures of plants produce?
The Female reproductive structures produce eggs. Eggs are fertilized by pollen.
How does reproduction continue after polination?
After pollination, the female flower parts form seeds. In most flowering plants, the seeds are contained within a specialized structure called a fruit.
How is pollination carried out? Examples?
Pollination occurs with the help of wind or animals.
Flowering plants, such as grasses and many common tree species,s are wind-pollinated.
In contrast, other flowering plants are pollinated by animals, such as insects, bats, and birds.
Fill in the blanks.
_____, ____, and ______ are not flowering plants. They have different sexual reproductive systems.
Mosses, ferns, and coniferous trees are not flowering plants. They have different sexual reproductive systems.
How are Conifers different from flowering plants?
Conifers are all wind-pollinated. Instead of having flowers, they produce pollen and seeds in specialized cones.
What is the purpose of a (flowering) plant’s stem/trunk?
The flowering plant stem (or trunk, in the case of trees) has several functions:
It supports the branches, leaves, and flowers and provides a way to transport materials. The stem contains significant amounts of vascular tissue for carrying substances to and from roots, leaves, flowers, and fruits.
Some stems are specialized for food storage, protection, photosynthesis, and reproduction.
What human products are dependent on plant stems
Sugar cane, potatoes, wood/paper products, cork, linen, and a variety of medicines?

What is the main photosynthetic structure of the plant?
The leaf is the main photosynthetic structure of the plant.
Light Energy + CO2 + Water ——> Glucose + Oxygen
What is the root system?
The system in a flowering plant, fern, or conifer that anchors the plant, absorbs water and minerals, and stores food.
What does the shoot system consist of?
It consists of the plant’s leaf, flower, and stem.
What is the purpose of the shoot system?
A system in a flowering plant that is specialized to conduct photosynthesis and reproduce sexually
