GRADED A+ 呼吸，是指生物体通过特殊的生理机制吸收氧气
并排出二氧化碳的过程。在人体内，这一过程由
what acquires nutrients from air water and soil - (answer)plants
呼吸系统完成，包括鼻腔、气管、支气管和肺部
等器官。有氧呼吸是指在氧气充足的条件下，细
what is 96% of plants' dry weight? - (answer)- organic carbon-containing compounds
胞利用葡萄糖分解产生能量；而无氧呼吸则是缺
乏氧气时的一种补偿机制。
how does a plant get carbon? - (answer)carbon comes from CO2 absorbed by plant leaves & integrated
into organic compounds (e.g., glucose) by photosynthesis
what do plants get from soil? - (answer)- water
呼吸，是生命存在的基本象征之一。无论是人类
- minerals 、动物，还是植物，呼吸都贯穿了所有生物体的
- some O2 生存过程。从吸入清新的氧气到排出废弃的二氧
化碳，呼吸不仅仅是生物体的生理行为，更是维
持生命的核心机制。本文将围绕呼吸这一主题，
what part of roots controls solute uptake? - (answer)The plasma membranes
从科学、自然、健康和技术等多个角度进行探讨
what must solutes move through to reach the water conducting xylem tissue at the center of the root -
(answer)must move through root epidermis & cortex
- this process involves passage across plasma membranes of root cells
plasma membranes are - (answer)selectively permeable, allowing entry of needed minerals and keeping
out unneeded or toxic substances
two possible routes to a plants xylem - (answer)1) intracellular
2) Extracellular
intracellular route to xylem is when... - (answer)water & solutes cross plasma membrane of root hair,
travel through passages (plasmodesmata) between cells to xylem
the extacellular route to xylem is when... - (answer)solution moves within cell walls and extracellular
spaces; does not cross any plasma membranes until it hits the Casparian strip
, 呼吸，是指生物体通过特殊的生理机制吸收氧气
What is the Casparian Strip and what does it do - (answer)- a continuous waxy barrier that stops water
and solutes from entering the xylem并排出二氧化碳的过程。在人体内，这一过程由
through cell walls
呼吸系统完成，包括鼻腔、气管、支气管和肺部
等器官。有氧呼吸是指在氧气充足的条件下，细
- forces water & solutes to cross a plasma membrane into an endodermal cell (the ring of cells around a
vascular bundle) 胞利用葡萄糖分解产生能量；而无氧呼吸则是缺
乏氧气时的一种补偿机制。
- this plasma membrane regulates mineral uptake for the the intercellular route.
what pulls water up xylem vessels - (answer)Transcription
呼吸，是生命存在的基本象征之一。无论是人类
、动物，还是植物，呼吸都贯穿了所有生物体的
what is Xylem sap composed of - (answer)water & minerals transported in xylem vessels
生存过程。从吸入清新的氧气到排出废弃的二氧
化碳，呼吸不仅仅是生物体的生理行为，更是维
持生命的核心机制。本文将围绕呼吸这一主题，
What is root pressure? - (answer)- when roots exert slight upward force on xylem sap by actively
pumping minerals into the xylem; water follows by osmosis
从科学、自然、健康和技术等多个角度进行探讨
- Root pressure is enough force xylem sap up a few meters
what is transpiration in relation to xylems - (answer)•-Transpiration is the loss of water from leaves •
- (1) Water exit leaves through stomata (singular stoma)
- then Water diffuses out of open stoma because outside air is usually drier than inside leaf. •
- which then creates a vacuum inside leaf.
- requires no energy from the tree
Is water cohesive or adhesive? - (answer)both.
, cohesive: because of hydrogen bonding which causes molecules to stick together
呼吸，是指生物体通过特殊的生理机制吸收氧气
并排出二氧化碳的过程。在人体内，这一过程由
adhesive: because it sticks to other surfaces
呼吸系统完成，包括鼻腔、气管、支气管和肺部
等器官。有氧呼吸是指在氧气充足的条件下，细
what within the xylem forms continuous strings from leaves to roots? - (answer)Cohering water
molecules 胞利用葡萄糖分解产生能量；而无氧呼吸则是缺
乏氧气时的一种补偿机制。
what allows water to be sucked up towards the leaves? - (answer)both the vacuum created by water loss
in leaves and the cohesion of water
呼吸，是生命存在的基本象征之一。无论是人类
whats does adhesions aid with in the xylem - (answer)helps counteract the downward pull of gravity in
、动物，还是植物，呼吸都贯穿了所有生物体的
xylem walls
生存过程。从吸入清新的氧气到排出废弃的二氧
化碳，呼吸不仅仅是生物体的生理行为，更是维
What do guard cells do? - (answer)- control transpiration
持生命的核心机制。本文将围绕呼吸这一主题，
从科学、自然、健康和技术等多个角度进行探讨
- since during dry conditions plants must retain water meaning they need to stop loosing water through
transpiration
- the cells open and close in order to control loss of water through the stomata
why do gaurd cells open during the day - (answer)to allow CO2 to enter leaf and fuel photosynthesis
why do guard cells close during the night? - (answer)to conserve water when there is no light to power
photosynthesis
What does Pholem do? - (answer)- transports sugars
- conducts phloem sap
- Sugar must be transported from sugar sources ( leaves) to sugar sinks ( parts of plant that are growing)
