this diagram illustrates the three types of plant tissue.
Which main plant tissues are the lines pointing to the enlarged diagram?
The main plant tissue that the lines in the enlarged diagrams point to is the ground tissue.
What are ground tissues in plants?Ground tissues in plants refer to the collenchyma tissues, the parenchyma tissues, and the sclerenchyma tissues.
In other words, they are tissues that are neither dermal nor vascular in origin.
Different ground tissues perform different functions depending on the part of the plants in which they are found. the functions range from photosynthesis in leaves to storage in roots, and support functions.

Tillage can release pollutants in the soil and
increase erosion.
decrease erosion.
promote soil compaction.
promote fertilizer retention.
Tillage can release pollutants in the soil and increase erosion by the acceleration of the soil and wind speed.
How doesTillage can increase erosion ?
Tillage can split soil structure, pace the decomposition and lack of natural matter, boom the hazard of erosion, break the habitat of useful organisms and reason compaction.
Each of those capability effects negatively effect soil fine. A soil's overall performance is immediately associated with a soil's fine or health. Since tillage breaks the soil, it disrupts soil structure, accelerating floor runoff and soil erosion. Tillage additionally reduces crop residue, which assist cushion the pressure of pounding raindrops.

What are the reactants and products for each step of photosynthesis and cellular respiration?
Answer:
Photosynthesis:
1) Reactants = CO2, Water, Sunlight
2) Products = O2, Glucose,
Cellular Respiration:
1) Reactants = O2, Glucose
2) Products = CO2, Energy
Explanation:
Hope this helps . Thank You !!!!
Answer:
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by-products and ATP is energy that is transformed from the process.

use the diagram above the distinguish between and to explain the terms cells, tissues, organs and systems. (350 words)
Answer:
I am unable to write 350 words but I can say this. Cells make up everything above, they are the building blocks. Cells make tissues, and tissues make organs.
Here in the image, the cells are the blood cells, the tissues are the smooth muscle tissue, loose connective tissue, columnar epithelium, nervous tissue, the organ is the stomach, the organ system is the digestive system, etc., and these are made up of cells.
What are the cells, tissues, and organ systems?Cells, such as the human blood cell, are the basic units of life; tissues, such as epithelial tissue, connective tissue, muscle tissue, nervous tissue, and so on, and organs, which are made up of different types of tissues that work together, such as smooth muscle tissues in stomach. Finally, different organs such as the stomach, the nervous tissues, etc. combine to make the digestive system, as explained here.
Hence, the cells are the blood cells, the tissues are the smooth muscle tissue, loose connective tissue, columnar epithelium, nervous tissue, the organ is the stomach, the organ system is the circulatory system, the digestive system, etc., and these are made up of cells.

light harvesting complex 1
Light-harvesting complex 1 captures the light energy from the sun and transfers it to the reaction center for the induction of redox processes.
How many types of light-harvesting complexes are there?There are two types of light-harvesting complexes which are most commonly known. LHC-I surrounds photosystem I, and LHC-II that surrounds photosystem II of the membrane.
LHC-I is dimeric in nature that is tightly bound to the photosystem I of the thylakoid membrane. It assists the photosystem I to receive the far-red light and releases its electrons.
Therefore, it is well described above.
