1: Chloroplasts play an important role in energy production in plant cells. However, some parts of a plant, like the roots, lack chloroplasts. In one to two sentences, explain the most likely pathway for root cells to obtain energy, and identify the organelles involved.
2: In three to five sentences, explain why animal cells do not require a cell wall or a central vacuole for their functions.
3: In three to five sentences, compare the process of digesting food in an amoeba (unicellular) to those in a mouse (multicellular) .
1: Root cells obtain energy through the process of cellular respiration, where they break down glucose to produce ATP. This process occurs in the mitochondria, which are organelles found in all eukaryotic cells, including plant cells. Roots lack chloroplasts because they are underground and do not receive adequate sunlight for photosynthesis to occur.
2: Animal cells do not require a cell wall because they do not need the rigid structure and support that a cell wall provides in plant cells. Instead, animal cells rely on intercellular junctions and extracellular matrix for support and communication. Similarly, animal cells do not need a central vacuole because they do not undergo the same turgor pressure changes that plant cells do, and they do not need to store nutrients or waste products in a central location like plants.
3: In an amoeba, digestion mainly occurs through phagocytosis, where the cell engulfs solid food particles and forms a food vacuole. Enzymes are then released into the vacuole to break down the food into smaller molecules that can be absorbed by the cell. In a mouse, digestion involves the mechanical breakdown of food in the mouth, enzymes breaking down food in the stomach and small intestine, absorption of nutrients in the small intestine, and elimination of waste through the large intestine. While both amoebas and mice digest their food to obtain nutrients, mice have specialized digestive organs and systems that allow for more efficient digestion and absorption of nutrients from a wider variety of food sources.
can u pls make all of them short
1: Root cells obtain energy through cellular respiration in the mitochondria, as they lack chloroplasts.
2: Animal cells do not need a cell wall or central vacuole because they rely on other structures for support and do not store nutrients in a central location like plant cells.
3: Amoebas digest food through phagocytosis, while mice rely on specialized digestive organs and systems for more efficient digestion and absorption of nutrients.
not that short but put all the info in a short sentence all of them
1: Root cells obtain energy through cellular respiration in mitochondria as they lack chloroplasts.
2: Animal cells do not require a cell wall or central vacuole as they rely on other support structures and do not store nutrients centrally.
3: Amoebas digest food via phagocytosis, while mice use specialized digestive organs for efficient nutrient absorption.
no make it longer
1: Root cells derive energy through cellular respiration in mitochondria, as they lack chloroplasts due to being underground without sufficient sunlight for photosynthesis.
2: Animal cells do not necessitate a cell wall or central vacuole because they depend on alternative support structures and do not store nutrients centrally as plant cells do.
3: Amoebas ingest and digest food through phagocytosis, engulfing solid particles and using enzymes to break down nutrients within vacuoles, whereas mice utilize specialized digestive organs to mechanically break down food in the mouth, enzymatically digest it in the stomach and small intestine, absorb nutrients in the small intestine, and excrete waste via the large intestine.
