Study Notes
Cell Structure and Components
- Vacuoles are fluid-filled spaces not occupied by cytoplasm.
- Robert Hooke discovered the cell, and Robert Browne discovered the nucleus.
- The nucleolus is located inside the nucleus.
Cell Wall and Composition
- The cell wall can be stained using an iodine solution, which also stains the vacuole and nucleus.
- The organized arrangement of cells in the cell wall of Allium cepa (onion) is due to cellulose.
- The cementing substance between cells is called the middle lamella.
- The middle lamella is composed of calcium, pectins, and magnesium.
Cellular Movement and Organelles
- The movement of green bodies (chloroplasts) is called cytoplasmic streaming or cyclosis.
- In this movement, chloroplasts move in a clockwise direction.
Specific Organelles and Plant Examples
- Chromoplasts are found in tomatoes.
- Amyloplasts, which store starch, are found in potatoes.
- The nucleus is visible in onions.
- Chloroplasts are present in Hydrilla verticillata.
- Tradescantia spathacea lacks vacuoles.
