Science Unit B: Unit 1 & 2 Flashcards
What are the processes that move water up from the roots?
Transpiration, capillary action, and osmosis
What is the process that moves water from an area of high concentration to an area of low concentration?
Diffusion
What is needed to produce seeds?
Pollen
What organisms help the pollination process?
Bees and ect.
How can some plants reproduce?
Some plants can reproduce by long stems that run along the surface of the soil called runners
How can growers reproduce plants?
By using cuttings, that are small pieces of wood that are connected to the stem
What do flowers do?
Each flower usually has both male and female parts for reproduction
What do the stems do?
Provide a pathway for movement of food and water
Support the leaves and reproductive structures
What do the seeds do?
Contain an embryo that will form a new plant
Contain a food supply for the embryo
What do the leaves do?
Produce food for the plant
Take in and release oxygen and carbon dioxide
Allow water to exit the plant
What do the cones do?
There are separate make and female parts
What do the roots do?
Absorb water and dissolve nutrients
Anchor the plant in the soul
Describe the process of transpiration
Water particles evaporate from the leaves and water particles move up and take their place, this process continues down through the plant with particle continually moving up through the roots
Describe the process of capillary action
It helps water move up through the plant. The water particles are attracted to each other. They are also attracted to the walls of the plant, thus helps water move up through the plant
What is the life cycle of a seed plant?
Seed➡️ (starts to grow) into seedling➡️(grow and develops reproductive structures) adult➡️
