Levels of interaction(plants)
includes:
chloroplasts (photosynthesis) mitochondria (cellular respiration) and the nucleus (contains genetic information).
What is an organelle?
Composed of leaves stems and flowers
What is the shoot system?
anchor the plant in the ground, absorb water and nutrients from the soil and transport them to the stem and leaves, store energy in the form of carbohydrates and help prevent soil erosion.
What are roots?
sepals
petals
stamens
pistil
What is the reproductive system in plants?
geotropism
phototropism
thigmotropism
hydrotropism
What are tropisms?
carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur are necessary for the formation of the 4 classes of biomolecules.
What is an atom?
Composed of roots, rhizomes, and tubers.
What is the root system?
underground stems that grow horizontally and produce roots and shoots at nodes. Allow the plant to spread out and reproduce asexually.
What are rhizomes?
These are green leaf-like structures at the base of the flower. They protect the flower during its development.
What are sepals?
This is the response of plants to gravity. The roots of plants exhibit positive ___, which means they grow downwards towards the center of the Earth. The stems of plants exhibit negative ___, which means they grow upwards against gravity.
What is geotropism?
includes leaves, stems, and roots.
What are organs?
main site of photosynthesis in a plant, where energy from sunlight is used to produce carbohydrates.
What are leaves?
Specialized structures that store energy in the form of carbohydrates (starch). Examples include potatoes carrots and yams.
What are tubers?
These are the colored structures that surround the reproductive parts of the flower. They are often brightly colored to attract pollinators such as bees, butterflies, and hummingbirds.
What are petals?
This is the response of plants to light. The stems of plants exhibit positive ___, which means they grow towards a light source.
What is phototropism?
group of the same oak tree species growing in a forest.
What is a population?
Provide support for the plant and transport water and nutrients from the roots to the rest of the plant.
What are stems?
Roots absorb water and minerals from the soil and transport them to the stem and leaves through the xylem. The leaves then use the water in the process of photosynthesis.
What is water?
These are the male reproductive parts of the flower. They consist of a filament and an anther, which produces and holds pollen.
What is the stamen?
This is the response of plants to touch. Examples of ___ responses include: tendrils coiling around objects for support roots growing around rocks in search of nutrients.
What is thigmotropism?
epidermal ____ (gas exchange, transpiration) , mesophyll ____ (photosynthesis) xylem _____ (water) phloem ____ (sugar).
What are tissues?
the reproductive structures of a plant, produces seeds through sexual reproduction, attract pollinators such as bees, butterflies, and birds
What are flowers?
Leaves produce this through photosynthesis and transport it to other parts of the plant through the phloem.
What is glucose?
This is the female reproductive part of the flower. It consists of the stigma, style, and ovary. The stigma is where the pollen lands, and the style is a tube that leads to the ovary. The ovary contains the ovules, which develop into seeds after fertilization.
What is the pistil?
This is the response of plants to water. The roots of plants exhibit positive ___, which means they grow towards sources of moisture.
What is hydrotropism?
