In a plant cell, how is the structure of the cellulose wall related to its function? Why are the structures of the cell wall and cell membrane important for the survival of humans and plants? Why don't animal cells have a cell wall?
Plant cells also have a central vacuole which contains water and maintains pressure against the inside of the cell wall. There are also plastids such as chloroplasts. Chloroplasts hold the chlorophyll which is the green pigment that gives plants color....

Previous work showed that compared to cationic porphyrins under light irradiation, the anionic ones were the strongest tobacco bright yellow cell death inducers. As this result was unexpected in light to literature, it was of importance to try to understand why anionic porphyrins were able to ...
extreme electronegativity of the fluoride ion a strong acid dissociate completely in water, it is more difficult to get it to separate from the hydrogen ion, so it will only partially dissociate in water, and is therefore considered a weak acid. However, ironically, the strong acid HF is ...
Protein is a structural macronutrient that is essential for various vital functions in the human body, including tissue growth and repair. Fat and carbs are energy sources, but the former is also vital for proper cell function, the creation of hormones, and many other metabolic processes. ...
Honey is made from bees collecting propolis, water and plant sap with their long pointed tongues. The little creatures have a separate stomach called the crop, where they store all the nectar until they get it back to the hive. This is done once their honey stomach is full; it’s a sep...

Place it in a sheltered, bright location with the aid of grow lights (ideally in a greenhouse or garage) and with a microclimate of 65-85°F. What Is the Lowest Temp a Tomato Plant Can Tolerate? According to the US Department of Agricultural Research, tomato plants can survive temperatures...
the leading edge of the oceanic plate bends into a slab that dives or "subducts" under the continent, triggering earthquakes and volcanism as the slabs descend into the mantle, which is like the bottom part of theconveyor belt. The subduction process is slow, with a slab averaging roughly ...
