front 1 What are root hair cells? Where is it located? What does it do? | back 1 Cells that take up water. it is located in the roots. It absorbs H2O and minerals from the soil and it is transported into the ylem vessels |
front 2 What is an adaptation of root hair cells? | back 2 They provide a large surface area to maximise amount of H2O taken up. |
front 3 What are root hairs? | back 3 A part of root hair cell that touches the soil. |
front 4 KIRTIESH REMEMBER IN EXAMS IF THEY ASK WHICH PART OF THE ROOT TAKES UP WATER, YOU SAY ROOT HAIR CELL NOT ROOT HAIR BECAUSE RHC IS BETTER. | back 4 OKAY BRO! |
front 5 What is the process in which H2O and minerals are absorbed to RHC? | back 5 Osmosis |
front 6 The process in which water moves from a place with high concentration
to a place with low concentration. | back 6 OSMOSIS! |
front 7 What are xylem vessels? | back 7 Vessels that transport H2O and minerals to the leaf from the root hair cells. |
front 8 How does water travel from the soil to the leaf? | back 8 Soil -> Root hair cells -> xylem vessels -> Leaf -> |
front 9 What is the root cap? | back 9 A structure that protects the tip of the root. |
front 10 What happens when water reaches the leaf? | back 10 Water reaches the leaf via the xylem vessels. Then, it enters the cell, where some of it is used for photosynthesis. most of it isn't used, so it soaks in the cell wall and evaporates to ebcome water vapour. Then, it diffuses through the air spaces and out of the stomata. |
front 11 Why is transpiration important for cooling? | back 11 When water in the leaf evaporates to become water vapour, it causes a cooling effect. |
front 12 Why is transpiration important for structure? | back 12 It provides water for cells to become turgid. |
front 13 Why is transpiration important for photosynthesis? | back 13 It provides water for photosynthesis. |
front 14 Why is transpiration important for transportation? | back 14 The water can transport mineral ions |
front 15 Why is water important for cooling? | back 15 When it evaporates, it causes a cooling effect. This allows the plant to stay cool, especially if it is found in hot places. |
front 16 Why is water important for structure? | back 16 It helps them to stand upwright and not wilt. |
front 17 Why si water important for transportation? | back 17 The water can transport the dissolved mineral ions |
front 18 Why is water imporatnt for photosynthesis? | back 18 It is needed to make glucose and oxygen. |
front 19 What is excretion | back 19 The process of removing waste products from the body |
front 20 Which system is responsible for this process? | back 20 Urinary system, renal system or excretory system |
front 21 What are the kidneys for? | back 21 Filter blood to seperate it with urea. Then it produces urea with excess water. |
front 22 What are the ureters for? | back 22 To transport the urine to the bladder, where it is stored. |
front 23 What is the bladder for? | back 23 To store urine until it is full. |
front 24 What happens when the bladder is full? | back 24 It sends signals to the body to use the bathroom. |
front 25 What is the urethra for? | back 25 To transport the urine out of the body. |
front 26 What is the pathway for the excretory system? | back 26 Kidneys -> Ureter -> Baldder -> Urethra -> |
front 27 How does the nutrients fromt he mother go to the fetus? | back 27 Nutrients from the mother's blood diffuses to tfhe fetus's blood. |
front 28 Why does a fetus need protein? | back 28 To produce new cells for the fetus's growth. |
front 29 WHy does a fetus need carbohydrates? | back 29 To supply it with energy |
front 30 WHy does a fetus need iron? | back 30 To rpoduce haemoglobin to transport oxygen |
front 31 Why does a fetus need calcium? | back 31 To make strong boens and teeth |
front 32 What harmful chemicals can the mother give the fetus if she smokes? | back 32 Carbon monixide and nicontine |
front 33 Why is nicontine bad for fetus? | back 33 It damages blood vessels |
front 34 Why is carbon monoxide bad for fetus? | back 34 It reducecs the amount of haemoglobin, therefore reducign the amount of oxygen. |
