Leaf Structure And Photosynthesis

dicotyledon

leaves have branching/net-like veins.

what are features of the internal structure of dicotyledons consist of?

epidermis

split mesophyll layer

vascular bundle

what are the main functions of leaves?

traps sunlight for photosynthesis

allows gaseous exchange to occur

transports water and minerals

how are bundles in a dicotyledon arranged?

in a ring

what root system does a dicotyledon have?

taproot system

what are the leave patterns called in a dicotyledon?

reticulate venation pattern

photosynthesis

The process by which green plants use light energy to convert carbon dioxide and water into glucose and oxygen.

what is the word equation for photosynthesis?

carbon dioxide + water → glucose + oxygen

what is the chemical equation for photosynthesis?

6CO2 + 6H2O → C6H12O6 + 6O2

what are the external adaptations that leaves have for photosynthesis?

broad and flat in shape

thin structure

leaf arrangements

what are the internal adaptations that leaves have for photosynthesis?

waxy cuticle

transparent upper epidermis

palisade mesophyll layer

spongy mesophyll layer

stomata and guard cells

vascular bundles

what are the factors that affect photosynthesis?

light intensity

carbon dioxide concentration

temperature

what is cellular respiration?

the metabolic process where cells break down food molecules and convert their chemical energy into usable energy, ATP

what happens to a cell when it needs energy?

ATP drops its third phosphate group, it turns int ADP and releases energy

why is ATP important in cells?

active transport

metabolic processes

cellular work

what is an ATP molecule made up of?

adenine

ribose

phosphate

what is aerobic respiration

cellular process in which living organisms use oxygen to break down food molecules, releasing energy, ATP while producing carbon dioxide and water as waste products

what is the word equation for aerobic respiration?

glucose + oxygen → carbon dioxide + water + ATP

what is the chemical equation for aerobic respiration?

C6H12O6 + 6O2 → 6CO2 + 6H2O + energy

what are the stages of glycolysis?

glucose is broken down into two 3 carbon pyruvate molecules in the cytoplasm

energy rich hydrogen atoms are released

small amount of ATP is released

co - enzymes carry energy rich hydrogen atoms to the next stage

what are the stages of the krebs cycle?

pyruvate atoms enter the mitochondrion

energy rich hydrogen atoms and CO2 are released

co - enzymes carry energy rich hydrogen atoms to the next stage

what are the stages of oxidative phosphorylation?

takes place in the cristae

energy rich hydrogen atoms are transferred from one hydrogen acceptor to the next

each time a hydrogen molecule is transferred energy is released

the energy binds a phosphate molecule with an ADP molecule to form ATP

what is anaerobic respiration?

the breakdown of glucose molecules to release energy without oxygen
