식물 다양성 소개
From Water to Land Kingdom Plantae first appeared about 410 million years ago as green algae transitioned from water to land. This land was a…
비관속 비종자식물
The diverse plant life on Earth—consisting of nearly 400,000 species—can be divided into three broad categories based on biological…
비종자 관속식물
Seedless Vascular Plants Were the First Tall Plants on Earth Today, seedless vascular plants are represented by monilophytes and lycophytes.…
종자식물 소개
Most plants are seed plants—characterized by seeds, pollen, and reduced gametophytes. Seed plants include gymnosperms and…
식물의 해부학적 구조: 뿌리, 줄기, 잎
The primary organs of vascular plants are roots, stems, and leaves, but these structures can be highly variable, adapted for the specific needs and…
식물 세포와 조직
Plant tissues are collections of similar cells performing related functions. Different plant tissues will have their own specialized roles and can be…
분열조직과 식물 성장
Plants grow throughout their lives; this is called indeterminate growth, and it distinguishes plants from most animals. Although certain parts of…
뿌리와 싹의 1차 및 2차 생장
Vascular plants, which account for over 90% of the Earth’s vegetation, all undergo primary growth—which lengthens roots and shoots. Many…
형태발생
Plant morphogenesis—the development of a plant’s form and structure—involves several overlapping developmental processes, including…
빛 획득
In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light…
물과 무기질 획득
Specialized tissues in plant roots have evolved to capture water, minerals, and some ions from the soil. Roots exhibit a variety of branching…
단거리 자원 수송
Short-distance transport refers to transport that occurs over a distance of just 2-3 cells, crossing the plasma membrane in the process. Small…
물관부 및 증산에 의한 자원 수송
The xylem of vascular plants distributes water and dissolved minerals that are taken up by the roots to the rest of the plant. The cells that…
기공을 통한 증산작용 조절
During photosynthesis, plants acquire the necessary carbon dioxide and release the produced oxygen back into the atmosphere. Openings in the…
물 손실을 줄이는 적응
Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions…
체관부와 당 수송
Like many living organisms, plants have tissues that specialize in specific plant functions. For example, shoots are well adapted to rapid growth,…
토양 생태계
Plants obtain inorganic minerals and water from the soil, which acts as a natural medium for land plants. The composition and quality of soil depend…
식물 영양의 핵심 요소
Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients…
식물 영양에서 박테리아와 곰팡이의 역할
Plants have the impressive ability to create their own food through photosynthesis. However, plants often require assistance from organisms in the…
착생식물, 기생식물, 식충식물
Plants often form mutualistic relationships with soil-dwelling fungi or bacteria to enhance their roots’ nutrient uptake ability.…
전세포벽과 전원형질
Plant growth depends on its ability to take up water and dissolved minerals from the soil. The root system of every plant is equipped with the…
