13520139373 | unicellular organism | Larger cells, survive in wider range of environments, need coordination to have organized function | 1 | |

13520139375 | Photosynthesis | Conversion of light energy from the sun into chemical energy. | 3 | |
13520139376 | cellular respiration | Process that releases energy by breaking down glucose and other food molecules in the presence of oxygen | 4 | |
13520139377 | Cuticle | Wach clear layer that prevents evaporation in the leaf | 5 | |
13520139378 | upper epidermis | the part of the leaf above the palisades layer that prevents the loss of water and is protective layer | 6 | |
13520139379 | Palisade tissue cells | column-shaped mesophyll cells in a plant leaf; responsible for photosynthesis and has lots of chloroplasts | 7 | |
13520139380 | Spongy tissue cells | photosynthetic plant cells that are loosely packed to enable gas exchange, located below the palisade tissue cells in a leaf | 8 | |
13520139381 | xylem and phloem | two types of vascular tissue | 9 | |
13520139382 | Xylem | carries water and minerals from roots to leaves | 10 | |
13520139383 | Phloem | Living vascular tissue that carries sugar and organic substances throughout a plant | 11 | |
13520139384 | lower epidermis | protective layer on the bottom of leaf which contains stomata & guard cells | 12 | |
13520139385 | Stomata | Small openings on the underside of a leaf through which oxygen and carbon dioxide can move | 13 | |
13520139386 | vascular bundle | a unit strand of the vascular system in stems and leaves of higher plants consisting essentially of xylem and phloem | 14 | |
13520139387 | Veins | Transport system is spongy tissue cells in mesophyll | 15 | |
13520139388 | Gas exchange | Happens in leaves, leaves are most important, spongy tissues cells and stomata | 16 | |
13520139389 | What happens to plants during gas exchange | Transpiration (guard cells and stomata keep the lead from losing too much water) | 17 | |
13520139390 | Transpiration | loss of water from a plant through its leaves | 18 | |
13520139391 | turgor pressure | water pressure within a plant cell | 19 | |
13520139392 | What happens during osmosis | Guard cells take in water, increase is turgor pressure and stomata opens | 20 | |
13520139393 | What happens during transpiration | Guard cells lose water, decrease in turgor pressure, stomata closes | 21 | |
13520139394 | Lenticels | A small raised area in the bark of stems and roots that enables gas exchange between living cells and the outside air. | 22 | |
13520139395 | What happens to the stomata with light | It opens | 23 | |
13520139396 | What happens to the stomata with no light | It closes | 24 | |
13520139397 | What are the functions of the xylem | - transport water and dissolved minerals - provides mechanical strength/support for the plant. It is made of dead cells that form a tube, without a xylem photosynthesis wouldn't happen | 25 | |
13520139398 | Water Uptake (Xylem) | Water enters plants through epidermal layer of root hairs, diffuses by osmosis, (mineral transport is active) | 26 | |
13520139399 | xylem sap | the water and dissolved minerals in the xylem | 27 | |
13520139400 | What are the functions of the phloem | Living cells, cell wall contains pores to exchange materials, transports sugars through plant | 28 | |
13520139401 | What are the 4 things that help sap travel up the stem | Cohesive forces, adhesive forces, root pressure, transpiration | 29 | |
13520139402 | cohesive forces | Attractive forces between water molecules | 30 | |
13520139403 | adhesive forces | Attractive forces between water molecules and surface molecules | 31 | |
13520139404 | root pressure | Turgor pressure inside the root xylem | 32 | |
13520139405 | Transpiration | Evaporation of water from the leaves of a plant and forces water up to replace evaporation | 33 | |
13520139406 | Sugar uptake (phloem) | Sugars (phloem sap), produced during photosynthesis transported through plant via photosynthesis. Sugar concentration through cell. Water moves into cell through osmosis, turgor pressure increases and forces sugar out of phloem to neighbouring cells | 34 | |
13520139407 | phloem sap | a mixture of sugar, nutrients, and water that flows through phloem vessels in a plant | 35 | |
13520139408 | Tropism | a plant's response to its environment | 36 | |
13520139409 | Phototropism | A growth response to light | 37 | |
13520139410 | Auxins | Plant hormones that lead to phototropism by elongating the dark side of the plant | 38 | |
13520139411 | Gravitropism | A growth response to gravity | 39 | |
13520139412 | negative gravitropism | growth of the plant stem upward, away from the earth | 40 | |
13520139413 | positive gravitropism | growth of the roots downward, toward the earth | 41 | |
13520139414 | nastic response | Response to touch (Venus fly trap) | 42 | |
13520139415 | sleep movements | Changes in the position of plant leaves throughout the course of a day, following the movement of the sun. Day leaves are high and full. Nighttime they drop. Controlled by turgor pressure | 43 |
