Photosynthesis & Chloroplasts Flashcards
What is Photosynthesis?, what are the three things that plants need for it to take place?
Photosynthesis takes place in almost all plant species , photosynthesis is the process where the plant makes it’s own food by converting light energy into chemical energy.Carbon Dioxide, water and light are the three things that plants need
What are chloroplasts ?
Chloroplasts are one of several different types of plastids, plant cell organelles that are involved in energy storage and synthesis of metabolic materials.Chloroplasts make sugars and starches.
what are the two different pigments that make a chloroplast green?
the two pigments that make a chloroplast green are chlorophyll A and chlorophyll B.
What is the use of the two green pigments in a chloroplast?
The pigments in a chloroplast absorb the light energy needed for photosynthesis to occur.
how many chloroplasts are there in a single photosynthetic cell?
There are 50-60 chloroplasts.
where can chloroplasts only be found?
Chloroplasts can only be found in plant cells.
how big is the density of a chloroplast on the surface of a leaf?
The density of a chloroplast on a surface of a leaf is about one-half million per square millimeter.
Why are chloroplasts disk shaped?
They are disk shaped so they can be more efficient in absorbing light of varying wavelengths.
Where does photosynthesis mainly take place?
It mainly occurs on the leaves of a plant but does still occur on plant stems and un-ripened fruit.
