Why do some flowers have so many pollen grains and ovules?
Answer:
The underlying as- sumption is that larger pollen grains contain more nutrients than smaller ones, at least those that store starch, and this allows their pollen tubes to grow through deep stigmas that can not be traversed by pollen tubes from small pollen grains. Pollen number and duration of stigma receptivity.

a chemist takes a polysaccharide and turns it into many disaccharide. what reaction has the chemist performed and what must he add
Answer:
hydrolysis
Explanation:
Water must be added to break the bonds in a polysaccharide, in order to become disaccharides and eventually monosaccharides.
Polysaccharides are composed of long polymerics of the monomeric sugars joined by linkages. A polysaccharide can be converted into a disaccharide by adding water through hydrolysis.
What is hydrolysis?The hydrolysis reaction is the chemical reaction that involves the breaking of chemical bonds by adding water molecules. The water acts as a nucleophile that eliminates, substitutes, and performs another process to break the bonds.
The polysaccharides are made by linking the monomers of the sugar that can be converted into disaccharides by adding water to the reaction so that it breaks the linkages between the sugar molecules to produce two sugar molecule structures. The large molecules produce smaller molecules.
Therefore, polysaccharides can be converted into disaccharides by adding water.

Other than carbon dioxide name two carbon compounds found in plants.
Answer:
See below.
Explanation:
Other than Carbon Dioxide (CO₂), two carbon compounds found in plants are :-
Glucose (C₆H₁₂O₆)Pyruvic Acid (C₃H₄O₃)The Calvin cycle, C3 pathway, or 3-phosphoglycerate photosynthesis are all names for the method by which plants fix carbon. PGA is a 3-carbon molecule.
What is the function of carbon in plants?The reasoning is simple Plants require atmospheric carbon dioxide to make food, and as a result of increased CO2 emissions from industry and autos, some crops and trees will grow bigger and faster.
Carbon is continuously exchanged between plants and the atmosphere. During photosynthesis, plants take up carbon dioxide, much of which is then stored in their roots in grasslands, and forests.
Therefore, Glucose and phosphoglycerate are the two carbon compounds found in plants.

List five cell organelles and describe their function.
Answer:
Ribosomes are tiny organelles that contain RNA and specific proteins within the cytoplasm. Within the cell, ribosomes are directly involved in the manufacture of proteins by using their RNA and amino acids.
This process involves decoding the information contained in the mRNA and using amino acids to produce the required proteins.
Mitochondria are some of the largest organelles within a cell.
Compared to some of the other organelles, mitochondria contain DNA which makes them semiautonomous. Mitochondria also contain a double-membrane with the inner membrane folding to form cristae.
Also known as the powerhouse, mitochondria play an important role in respiration where they generate ATP (adenosine triphosphate) from substrates in the presence of oxygen. Using their DNA, mitochondria are able to encode for some of the components they require to perform their functions.
The plasma membrane is the organelle that encapsulates the contents of the cell. Apart from encapsulating cell contents, the plasma membrane also plays a vital role in regulating the movement of substances in and out of the cell.
As such, it is actively involved in such both passive and active transportation to and from the cell. These processes also help maintain balance even when conditions outside the cell change.
The plasma membrane is made up of two layers of phospholipids (phospholipids bilayer).
Found in eukaryotic cells, Endoplasmic reticulum (ER) is the organelle that forms an interconnected network of flattened sacs (cisternae). Like some of the other organelles found in eukaryotes, ER is enclosed in a membrane. The ER is divided into two regions that vary in structure and function.
These include:
Smooth endoplasmic reticulum - The smooth ER is named so because it lacks a ribosome on its surface. As a result, it is more smooth in appearance as compared to the rough ER. It is involved in the synthesis of lipids (e.g. phospholipids) and carbohydrates that are used to build the cell membrane.
Stromatolites are single celled prokaryotic bacteria cells.
