Biology Unit 2 Module 2 1.1: Explain the uptake of ions by active transport in roots; * Emphasize the role of the endodermis. Most plants secure the water and minerals they need from their roots. The path taken is: soil -> roots -> stems -> leaves The minerals (e.g.‚ K+‚ Ca2+) travel dissolved in the water (often accompanied by various organic molecules supplied by root cells).Less than 1% of the water reaching the leaves is used in photosynthesis and plant growth. Most of it is

OF PLANT STRUCTURE Adonay‚ Jessa and Velos‚ Mary Angelie Biology Program‚ Sciences Cluster University of the Philippines Cebu Lahug‚ Cebu City‚ Philippines ABSTRACT Plants have essential requirements to survive like all other living being. Roots‚ stems‚ leaves‚ and flower serve to help them acquire or provide for these requirements. Plants exposed to different climates pose different arrangement in the structures’ tissues. A closer look on its cellular level and we could understand this

the 18th century that plants absorb mineral nutrients as inorganic ions in water. Normally soil is thought to be required for plant growth‚ but in actuality‚ soil is not needed at all. When the mineral nutrients in the soil dissolve in water‚ plant roots have the ability to absorb them. When the required mineral nutrients are introduced into a plant’s water supply artificially‚ soil is no longer required for the plant to thrive. Almost any terrestrial plant will grow with hydroponics. Hydroponics is

The plumeria is from the tropical Caribbean lslands and is by far the most beautiful flowering tree. lt can be grown all over the world because it has a very small root system. Since the plumeria only grows to the size of the container‚ it makes a beautiful potted plant for the patio‚ screen pool‚ balcony or driveway - blooming all summer long. ln the fall‚ when the temperature starts to drop‚ the plumeria will start

direction. Different parts of a plant exhibit different reactions to light. Stems exhibit positive phototropism while most roots exhibit negative phototropism. Geotropism is the growth response of a plant in response to gravity. Roots exhibit positive geotropism while stems and leaves exhibit negative geotropism. Hydrotropism is the growth response of a plant to water. Roots exhibit positive hydrotropism. Thigmotropism is the growth response of a plant to physical contact (touch). Plants that

mangrove trees must withstand being submerged twice a day by saltwater tides. The soil in which these trees grow in maybe sand but it is mostly rich mud. This rich mud is high in nutrients but low in oxygen. Mangroves have these aerial and salt filtering roots and salt excreting leaves that help them occupy the fluctuating wetlands. Salinity‚ temperature and oxygen are all abiotic factors used to help with the growth of this ecosystem. Salinity is a measurement of the amount of salt in the water. To

leaves travels down stems to the roots. Stems also store food for the plant. Roots: These anchor plants in the soil. Water and minerals are taken from the soil through the roots. Many plants such as carrots‚ store food in their roots. Seeds: these contain a tiny embryo of a plant inside. The seed halves contain food‚ which supplies energy and materials for growth until the plant grows its first leaves above the ground. ROOT In vascular plants‚ the root is the organ of a plant that
