What are the materials needed for plant processes
food, water, and oxogen to survivive
what carries water and food to all parts of the plant in a plant
vascular structures
what happens to water in a plant
water is absorbed by the roots and travel xylen to all cells
why do plants welt
plants welt without enough water becuase needed water is taken from individual cells
where is food made in leaves and where does it travel
food is made in the cells of leaves amd travels through phloem throught the plant
what happens to gasses such as carbon dioxide, oxogen and water vapor in plants
these gases are taken in and released by the leaves of plants through small holes called stomata
what is photosythesis
the process of how a cell captures sulight and usues it to make food
what are leaves of a plant designed for
designed for photsythesis
what is a cuticle
waxy layer to limit evaporation
what is stomata
small opeings where gases can enter/exit
what does the mesophyll layer conatin
conatin chloroplasts
what are chloroplasts
orgenells where photosythesis takes place
what is palisade mesophyll layer like
near the top and tightly packed, and exposes most cells to light
what is spongey mesophyll like
has more space between cells to let gases in/out
how do plants capture light energy
in the cholorplasts are pigments that can capture the light
what is the most common pigment
chlorophyll
why do plants appear green
becuase phlorophyll reflects green light
how do plants make sugar
carbon dioxide is combined with water in the chlorplasts to create a type of simple sugar called glucose
why do plants need suagr
plants use sugar as their energy source
how do plants produce sugar
use captured light to produce sugars
what is the 4 step process of plants using energy to make food
• plants absorb water from the soil through their roots 2. carbon dioxide enters through stomata-opening in leaves. 3. the water and carbon dioxide enter the chlorplasts in leaf cells. 4. in the cells, these 2 compounds combine to produce sugar and oxogen
what is the photosythesis equation
light 6CO2 + 6H20 —> C6H1206 + 602
what is cellular resperation
a series of chemical reactions that convert the energy in food molecules into a usable form of energy called ATP
what is gluecose broken down to make
broken down to make ATP, a storage molecule
