II1. Kingdom Plantae movements would relate to time of day or weather patterns and movement of the chloroplasts within an Elodea cell as their 2. Describe nergy? the process and name the organelle by which plants turn light into e 3. Cite two examples of structures/organelles that are found in plant cells but not in animal cells 4. What substances are found in the cell walls of plants? 5. Why would animal cells and some protists not require a cell walls but plants, fungus, other protists, and monerans require a cell wall structure?Explanation / Answer
1. Movement of chloroplast in Elodea cells is referred to as cyclosis. Chloroplast moves in cells by chloroplast actin filaments that is polymerised by chloroplast unusual positioning 1 at the front side of the moving chloroplast. In Elodea, chloroplast will slide and scoot often at the edges of the cell but sometimes it will cover the entire parts of the cells with a constant motion. Movement of chloroplast varies with changes in light intensity or changes in fluid content in cells.
2. Leaves plays important role in converting light in to energy. It will absorb sun light and carbon dioxide and will convert into energy called glucose and in turn will release oxygen in to atmosphere.
3. Organelles present in plant cells but not in animal cells are cell wall, chloroplast and vacuoles.
4. Substances present in plant cell wall is pectin, cellulose and hemicellulose.
