Unit B Section 1 Flashcards
Transport water and nutrients. Support the leaves. Stores the food
The function/structure of a stem is…
Produces food by taking in sunlight and turning it into chemical energy. Absorbs Oxygen and releases Carbon Dioxide. Water leaves and enters through the guard cell/stoma/stomata
The function/structure of a leaf is…
They contain an embryo that will form a new plant. They also contain a food supply for the embryo.
The function/structure of a seed is…
The function of a cone/flower is…
Both cones and flowers have male and female parts for reproduction.
When particles move from an area of high concentration to low concentration.
Diffusion
When the concentration of water in the soil is greater than the concentration of the water in the roots, water moves into the root cells.
Osmosis
Water particles evaporate from the surface of the leaves and more water particles move up within the plant to take their place.
Transpiration
This attraction causes water particles to ¨stick” together and move up inside the plant, moving against gravity.
Capillary Action
The energy of the sun is trapped in the leaves and changed into chemical energy. Carbon dioxide and water are used by the leaves in the process called … to make sugar and give off oxygen.
Photosynthesis
Plants release carbon dioxide and let oxygen into their cells.
Cellular respiration
Growth is very fast producing new leaves, roots, stems and their own food. Still need nutrients from the soil.
Seedling stage
When a plant produces reproductive structures.
Adult stage
Contains the female part of the flower.
Ovary
Male part of the flower. Where the pollen is deposited.
Stigma
Is what attracts the pollinators.
Nectar
