What are the differences between apoplast and symplast in plant cells and how do they contribute to the movement of water and nutrients within the plant?
Apoplast and symplast are two pathways for water and nutrient movement in plant cells. The apoplast is the space outside the cell membrane, including cell walls and intercellular spaces, while the symplast is the interconnected network of living cells through plasmodesmata.
Water and nutrients can move through the apoplast by following a continuous path through the cell walls and spaces between cells. In contrast, the symplast allows for movement through the living cells themselves via plasmodesmata, which are channels that connect the cytoplasm of adjacent cells.
The apoplast pathway is faster but less selective, while the symplast pathway is slower but more controlled. Both pathways work together to efficiently transport water and nutrients throughout the plant, with the apoplast facilitating rapid movement and the symplast ensuring regulation and selectivity.
What else can I help you with?
Does osmosis occur in apoplast and symplast pathwaywhy?
Osmosis primarily occurs in the symplast pathway, as water moves through the living cells of the plant via plasmodesmata. The apoplast pathway, which involves movement of water through the cell walls and intercellular spaces, does not involve osmosis because osmosis requires a selectively permeable membrane, which is absent in the cell walls.
Why does water flow and what factors contribute to its movement?
Water flows due to the force of gravity pulling it downhill, as well as the pressure differences created by uneven terrain and obstacles in its path. Factors that contribute to water movement include slope gradient, channel shape and size, amount of water present, and the presence of obstacles like rocks or vegetation.
What is the name if the movement of nutrients in the cells?
The movement of nutrients within cells is called intracellular transport. This process involves the movement of molecules and substances within the cell to where they are needed for cellular functions.
What is cellular growth movement of nutrients and wastes as a cell size increases?
Cellular growth involves an increase in cell size due to the uptake of nutrients and the removal of wastes. As a cell grows, it requires more nutrients to support its increased metabolic activities, and wastes must be transported out of the cell to maintain proper function. This movement of nutrients and wastes is crucial for the health and function of the cell.
What are the differences between transpiration and translocation?
transpiration is the evaporation of water through leaves and stem. translocation is the transport of sugars in a plant. Translocation- movement of food and nutrients in the plant Transpiration- loss of water through leaves via stomates
What is apoplasmic and symplasmic nuturient movement?
Apoplasmic nutrient movement refers to the transport of substances through the apoplast, which is the network of cell walls and intercellular spaces, allowing nutrients to move without crossing cell membranes. In contrast, symplasmic nutrient movement occurs through the symplast, which consists of the cytoplasm of living cells connected by plasmodesmata, allowing nutrients to flow directly from cell to cell. Both pathways play crucial roles in the uptake and distribution of nutrients in plants.
Does osmosis occur in apoplast and symplast pathwaywhy?
Osmosis primarily occurs in the symplast pathway, as water moves through the living cells of the plant via plasmodesmata. The apoplast pathway, which involves movement of water through the cell walls and intercellular spaces, does not involve osmosis because osmosis requires a selectively permeable membrane, which is absent in the cell walls.
The movement of material due to differences in density that are caused by differences in temperature is called what?
The movement of material due to differences in density caused by differences in temperature is called convection.
Deep currents are the result of?
Deep currents are the result of differences in water density caused by variations in temperature and salinity. These differences create a gradient in density which drives the movement of water at depth in the ocean. The movement of deep currents plays a crucial role in transporting heat, nutrients, and oxygen around the world's oceans.
Two ways circulatory system contribute to muscle movement?
The circulatory system carries nutrients and oxygen to the muscles that need them. It also carries waste dispelled by muscles away from them.
What is the difference between symplast and apoplast?
The apoplast and symplast pathways are two different pathways by which water can move through the root of a plant. Water in the apoplast pathway moves from cell to cell via spaces in the cellulose cell walls until it reaches the endodermis. At the endodermis, there is the 'apoplast block' - the cellulose cell walls of the cells of the endodermis have a substance called suberin which is impermeable and prevents the movement of water. The suberin makes up what is called the Casparian strip. At this point, all the water has to move into the vacuolar and symplast pathways. The function of the apoplast block is to prevent harmful substances from entering the xylem. The symplast pathway is where water moves from cell to cell in the cytoplasm via the plasma membranes and plasmodesmata. Water moves along the root by osmosis down a water potential gradient (as water moves into one cell, this cell then has a higher water potential than the adjacent cell, so water moves from cell to cell by osmosis). Water moves in this way along in the cytoplasm from the root hair cell to the endodermis.
What effect does the heating of the earth have on air and water movement?
it moves a lot!
What is the intercellular area between root epidermal and cortical cells?
The intercellular area between root epidermal and cortical cells is known as the apoplast. This space allows for the movement of water and solutes between cells without passing through the cell membranes, facilitating nutrient uptake and transport. It plays a crucial role in root hydration and the overall absorption process in plants. Additionally, the apoplast can serve as a pathway for pathogens to enter the root system.
