3. Food (Sugar)
Four (4) basic needs of plants
Two Major Classifications of plants
Plants that have tube-like structures that run through the plant transporting water, minerals, and sugar. Can grow to be tall. (examples: Trees, Flowers, Shrubs, Grass)
Plants that do not have tube-like structures. Must absorb water and minerals through their cell walls. Grow low to the ground. (examples: moss, liverwort, hornwort)
Vascular tissue found in vascular plants, responsible for transporting sugar through the plant ("FOOD FLOWS from the top down")
Vascular tissue found in vascular plants, responsible for transporting water and minerals from the roots and up throughout the plant.
Root-like structures found on Non-vascular plants, responsible for anchoring the plant.
Plants that reproduce with SPORES instead of seed & pollen. (Examples: most nonvascular plants and Ferns)
Plants that reproduce with seeds (eggs) and pollen (sperm).
Two (2) types of seed plants.
A seed plant that produces CONES. The seed is not protected by a thick coat (Naked Seed). They have separate cone clusters that produce pollen (male gamete), and cone clusters that produce the seeds (female gamete).
A seed plant that produces FLOWERS. The flower contains both pollen (male gamete) and seeds (female gamete). The flower typically will become some form of fruit or nut.
3. Insects (Bees)
4. Other animals carrying or eating, then depositing later.
Four (4) ways that seeds & pollen can be dispersed.
Pollen being transported from one flower to another.
The point when the pollen and the seed join.
The point when the seed begins to sprout.
The fertilized seed.
The baby plant that grows within the seed.
Angiosperm plants that only have one (1) lifecycle or growing season. (ex: marigolds, petunias, pansies)
Angiosperm plants that live only two (2) years. (Ex: Celery, Parsley).
Angiosperm plants that flower year after year. (Ex: Tulips, Roses, Fruit Trees)
The hard, protective layer on the outside of a seed.
The seed leaf. It is the food source for the baby plant. It is usually the "meaty" portion of the seed.
Angiosperm plants with only one (1) seed leaf. Sprouts only one (1) leaf upon germination. Its flower petals will grow in multiples of three (3).
Angiosperm plants with two (2) seed leaves. Sprouts two (2) leaves upon germination. Its flower petals will grow in multiples of 4 or 5.
The anchor for plants. Also is responsible for drawing up water and minerals from the ground.
The protective covering over the tip of a root to prevent damage while growing.
The leaf-like structure that covers and protects the flower bud, and becomes the stage for the flower bloom.
The colorful part of the flower - shapes and size vary from flower to flower.
The male part of the flower. It is composed of both the Filament & the Anther. The anther is where the pollen is produced.
The female part of the flower. It is composed of:
1. Stigma: the opening
2. Style: The tube-like stem
3. Ovary: The hollow, bowl-like structure that holds and protects the seed while it develops.
The plant's tendency to grow towards or away from a stimulus.
Gravitropism or Geotropism
Roots grow down towards the gravitational pull and the stems grow up away from the gravitational pull.
The tendency for a plant to grow towards the sunlight. (Example: Sunflower)
The plants growth in response to touch. (example: a Vine plant will coil around what it touches in order to expand and grow up walls, poles, trees, and other plants.)
The ability for a plant to "Hibernate" to withstand harsh conditions such as freezing temperatures. (Deciduous trees, Grasses, Flowering plants, etc.)
A layer of plant cells where new phloem and xylem are produced.
Pore-like openings in plant leaves that allow gases & water in & out of the plant.
