unit b section 1 Flashcards
what is a function/structure of a stem
Transports water and nutrients, supports the leaves, stores food
what is the function/structure of a leaf
Produce food from collecting energy from the sun ,take in carbon dioxide and releases oxygen, water enters and leaves the cells of the leaves.
whats the function/structure of a seed
contains embryo that forms a seed that contains a food for the supply of an embryo
whats the function of a cone/flower is
Both cones and flowers have male and female pats for reproduction
Osmosis
water from the soil enters the root cells
Diffusion
diffusion______ happens when there is a difference in concentration. Particles move from an area of __high___ concentration to ___low__ concentration. Ex - food colouring in water or perfume in a room
Capillary action
Another process that helps water ___move up________ through a plant is called __capillary___________ __action
Transpiration
Water particles evaporate from the surface of the leaves and more water particles move up within the plant to take their place.
Photosynthesis
the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
(Carbon dioxide+water+sunlight=photosynthesis)
cellular respiration
Cellular respiration is the process by which cells derive energy from glucose
seedling stage
a young plant still reliant on food reserves stored in the seed
adult stage
when the plant is grown and fully developed
ovary
female part of the flower
stigma
male part of of the flower and its where the pollen is deposited
nectar
a viscous, sugar-rich liquid produced by plants in glands called nectaries
