plant Flashcards
what are the products of photosynthesis
glucose and oxygen
how does the carbon dioxide enter the plant
carbon dioxide enters the plant through the holes in the leaves called the stomata
how does water enter the plant
water diffuses into the plant through the roots from the soil and travels up the stem via the xylem
What is the chemical equation for glucose
C6H12o6
why is photosynthesis an endothermic reaction
because it requires energy to be transferred from its surroundings
what is the purpose of the vascular bundle
to transport water and sugar
what is the purpose of palisade mesophyll
packed with chlorophyll and chloroplast which is where photosynthesis occurs
what is the purpose of the cuticle and epidermis
the waxy cuticle, produced by the epidermis cells, seals up the leaf to stop it from drying out
what is the purpose of the spongy mesophyll
plenty of space, allows the movement for CO2
what is the purpose of a stomata
to let the gas in and out of the leaf and to prevent bacteria from getting into the leaf
why do plants need potassium
for healthy plants and flowers
why do plants need magnesium
to make chlorophyll
what factors affect the rate of photosynthesis
light intensity, carbon dioxide concentration, amount of water, temperature
bubbles are produced by water and plants. What gas are these bubbles made up of
The bubbles are made up of oxygen. We know this because oxygen is a product of photosynthesis
what is the law of conservation of mass
matter can’t be destroyed or created. It always stays the same
what do all carbohydrates have in common
they all provide energy
what is the word equation for photosynthesis
carbon dioxide + water —–> glucose + oxygen in the presence of sunlight
where exactly in the plants does photosynthesis take place
chloroplast
do you think variegated leaves are efficient at converting sunlight into starch
variegated leaves have a weaker green pigment in some areas. The green pigment comes from chlorophyll, which is responsible for converting sunlight into glucose then starch. So because, with a lack of chlorophyll, variegated leaves are not efficient at converting sunlight to starch.
what are the characteristics of all living organisms
MRS GREN : movement, respiration, sensitivity, growth, reproduction, excretion and nutrition
what do the roots do
the roots absorb water and inorganic nutrients
what does the leaf do
performs photosynthesis
what does the stem do
supports the plant
what is the purpose of transpirtation
to control the temperature and the flow of nutrients to the leaves in a plant
how are decomposers important to plants
decomposers feed on dead things around plants. They break apart the dead materials and make the vital nutrients for plants, this will help the plants grow.
what is the process of plant losing water called
transpiration
why is transpiration important for plants
because it stores water for the plant when there isn’t enough water
what does it mean when guard cells become flaccid
it means that there is little water in the soil, and the cells have decreased in size because of the loss of water.
what does it mean when guard cells are turgid
it means that there is a lot of water in the soil for the cells to soak up and the cells become larger and open
