Stroma
Fluid in between grana, where carbohydrate-formation reactions occur in the chloroplasts of plant cells photosynthesizing.
-
Thylakoid
- Site of the light-dependent reactions of photosynthesis.
- Form stacks of disks referred to as grana.
- Thylakoid membrane surrounding a thylakoid lumen.
-
Grana
Stacks of thylakoids.
-
Leucoplasts
- A category of plastid.
- They are non-pigmented.
- They are white and colorless, so they are located in roots and non-photosynthetic tissues.
- Specialized for bulk storage of starch and lipids and are then known as amyloplasts and elaioplasts.
-
Parenchyma
The ground tissue ofnonwoody structures.
-
Epicotyl
- Stemlike shoot above the cotyledons attached at the hypocotyl.
- In most plants the epicotyl will eventually develop into the leaves of the plant.
- Includes plumules.
-
Plumule
- The rudimentary terminal bud of a plant embryo situated at the end of the epicotyl, consisting of the epicotyl and often of immature leaves.
- Forms the shoot of the plant.
-
Radicle
The embryonic root of the plant, and grows downward in the soil.
-
Hypocotyl
Stem of a germinating seedling, found below the cotyledons and above the radicle.
-
Meristem
The undifferentiated plant tissue from which new cells are formed, as that at the tip of a stem or root.
-
Apical meristem
- A meristem at the tip of a plant shoot or root that causes the shoot or root to increase in length.
-
-
Lateral meristem
- A meristem in vascular plants, such as the cambium, in which secondary growth occurs.
