Plant Nutrition (B6)
This green pigment is responsible for trapping light energy from the Sun to manufacture carbohydrates.
What is chlorophyll?
This type of digestion involves the breakdown of food into smaller pieces without chemical change to the food molecules.
What is physical digestion?
These dead, hollow vessels transport water and mineral ions one-way from the roots to the leaves.
What are xylem vessels?
These blood vessels have thick, muscular, elastic walls to withstand the high pressure of blood being pumped away from the heart.
What are arteries?
This type of reproduction results in offspring that are genetically identical to the parent.
What is asexual reproduction?
This is the site of female gamete (egg) production and the release of oestrogen and progesterone.
What are the ovaries?
The balanced chemical equation for photosynthesis shows that this many molecules of Carbon Dioxide and Water are needed to produce one molecule of Glucose.
What is six (6)?
Produced in the liver and stored in the gall bladder, this substance emulsifies fats to increase their surface area for digestion.
What is bile?
This process is the loss of water vapor from plant leaves by evaporation of water at the surfaces of the mesophyll cells followed by diffusion of water vapor through the stomata.
What is transpiration?
This side of the heart has a much thicker muscular wall because it must pump blood at high pressure to the entire body.
What is the left side (left ventricle)?
In a flower, this is the transfer of pollen grains from the anther to the stigma.
What is pollination?
This organ allows for the exchange of nutrients, gases, and waste products between the maternal blood and fetal blood without them mixing.
What is the placenta?
Daily Double!!!
Plants often convert glucose into this insoluble polysaccharide for long-term storage in the roots or stems.
What is starch?
This enzyme is secreted by the salivary glands and the pancreas to break down starch into maltose.
What is amylase?
This specialized cell has a long extension that increases its surface area for the efficient absorption of water and minerals from the soil.
What is a root hair cell?
These cell fragments in the blood are essential for the process of blood clotting and scab formation.
What are platelets?
These are the three environmental conditions required for most seeds to germinate.
What are water, oxygen, and a suitable temperature?
This hormone, produced in the testes, is responsible for the development of secondary sexual characteristics in males during puberty.
What is testosterone?
These two specific ions are required by plants: one for making amino acids and the other for making chlorophyll.
What are nitrate ions and magnesium ions?
These finger-like projections in the small intestine increase the surface area for the absorption of digested food.
What are villi?
This term refers to the transport of sucrose and amino acids in the phloem from a "source" to a "sink."
What is translocation?
This is the name of the vein that carries deoxygenated blood from the body back into the right atrium of the heart.
What is the vena cava?
This structure grows down the style to the ovary to allow the male nucleus to reach the female nucleus in the ovule.
What is a pollen tube?
Daily Double!!!
HIV is a pathogen that can cause AIDS by infecting and destroying these specific types of cells in the immune system.
What are lymphocytes?
This term describes a factor that is in such short supply that it restricts the rate of photosynthesis, such as low light intensity or temperature.
What is a limiting factor?
This specific part of the villus is responsible for the absorption and transport of fatty acids and glycerol into the lymphatic system.
What is a lacteal?
Water molecules are held together by these forces, creating a continuous "suction" or "pull" that moves the transpiration stream upwards.
What are cohesion forces?
This soluble plasma protein is converted into insoluble fibrin threads to form a mesh that traps red blood cells during clotting.
What is fibrinogen?
This term describes the fusion of the nuclei from a male gamete (pollen) and a female gamete (ovule).
What is fertilisation?
This hormone is released by the pituitary gland and stimulates the follicles in the ovaries to develop at the start of the menstrual cycle.
What is FSH (Follicle Stimulating Hormone)?
