Plant Cell Specialization + Photosynthesis Flashcards
(14 cards)
What is plant cell specialization
Cells and structures that have specialization
Examples: root hairs, guard cells, stomata
What are root hairs
Tiny hair-like projections that absorb water and minerals from soil
What are guard cells and their function
Found on the underside of the leaf, they swell and contract to control gas exchange through the stomata
What is the stomata and its function
Are pores formed by guard cells that allow gases to pass through
What is the main purpose of leaves and what kind of specialized cells do they have
Main purpose is to carry out photosynthesis
They have specialized cells that are densely packed with chloroplasts (organelle)
What are chloroplasts and their function
Are the organelles
They carry out photosynthesis
Contains a green pigment (chlorophyll) which traps light
What do the separate words ‘photo’ and ‘synthesis’ mean
Photo = light
Synthesis = putting together
What is the process of photosynthesis
Conversion of carbon dioxide from the air and water from the soil to create sugar and oxygen
Where does photosynthesis occur
In the palisade cells
Can photosynthesis occur in the dark?
No, it cannot be done in the dark it NEEDS light to happen
What is the written and formula equation for photosynthesis
Written:
Water + carbon dioxide + energy
=
glucose + oxygen
Formula:
6 H(2)O + 6 CO(2) + energy
=
C(6)H(12)O(6) + 6 O(2)
numbers in brackets are subscripts
Where does cellular respiration occur
Occurs in all organisms
Occurs specifically in the mitochondria of all cells
What is the process of cellular respiration and what is it needed for
Conversion of sugar and oxygen into water and carbon dioxide
Is needed to produce the useable form of energy (ATP)
What is the written and formula reaction for cellular respiration
Written:
Glucose + oxygen
=
Water + carbon dioxide
Formula:
C(6)H(12)O(6) + 6 O(2)
=
6 H(2)O + 6 CO(2)
numbers in brackets are subscripts
Essentially cells take in oxygen and break down glucose (for energy) and release water and carbon dioxide
