What are the external parts of stem?
The external parts of a stem include the epidermis (outermost layer), the cortex (region beneath the epidermis), vascular bundles (tissue that transports water and nutrients), and the cuticle (waxy layer that helps prevent water loss).
External parts of stem?
the stem consists of the outer dermal tissues which has epidermis. also it has the vascular system, which is made up of xylems and pholoems. Xylems transports the liquids aroudn the plant while the pholoems transports all the food. there are different structures of the vascular tissues through out the plants. between the vascular tissues and the dermal tissues there is the ground tissue.
What is the external part of stem and their function?
Lenticel - it function as a pore, providing a medium for the direct exchange og gases between the internal tissues and atmosphere. Axillary bud - are buds that develop from the nodes which then becomes a new stem. Terminal bud - is the main area of growth in most plants. Lateral bud - it is capable of developing into a branch shoot or flower cluster. Leaf scar - is the mark left on a stem after a leaf falls. Internode - space between two node. Node - hold buds which grow into one or more leaves, inflorescecne (flowers), cones or other stems etc.
What is does the stem port mean?
The term "port" typically refers to a connection point for external devices to a computer or network. In relation to "stem port," it could be a designated port on a networking device, such as a switch, that is used to forward traffic between different network segments or VLANs. This port plays a crucial role in handling communication between different parts of a network.
Drawing of the label the external part of a leaf?
at the external layer is the lamina which is the flat leaf. there is also the network of veins which provides the minerals.furthermore is the petiole which holds the leaf the the main branch.lastly is the cuticle which prevents excessive loss of water of the plant. this is the internal structure of the leaf courtesy from www.wikipedia.org HI

What is pliant stem?
A pliant stem is a stem that is flexible and easily bends without breaking. This flexibility allows the stem to sway with the wind or other external forces, providing support and reducing the risk of damage. Examples of plants with pliant stems include bamboo and certain types of grasses.

What can stem cells do that other cells can not do?
Stem cells has the capability to regenerate and develop into any kind of tissue or organ, when supported with the external nutrients. So they are called as totipotent. There are two kinds of stem cell a)adult stem cells b)embryonic stem cells. There are various researches going on in this area .
Why don't the the stem cells differentiate fully?
Stem cells have the ability to differentiate into different cell types, but external signals from the surrounding environment influence this process. Factors such as growth factors and neighboring cells play a role in directing stem cell differentiation. If the signals are not present or are disrupted, stem cells may not differentiate fully into the desired cell type.
What produces cells to cover the stem and root surfaces?
The epidermis is responsible for producing cells to cover the stem and root surfaces in plants. These cells provide a protective barrier that helps prevent water loss and protects the plant from external threats such as pathogens.

Explain why a thermometer thick walls on its stem?
Thick walls on the stem of a thermometer provide insulation and reduce heat transfer from the environment, resulting in more accurate temperature readings. This helps to prevent external factors, such as air temperature fluctuations, from affecting the measurement inside the thermometer.
Why does A thermometer have thick walls on it's stem?
Thick walls on the stem of a thermometer help to insulate the temperature sensor from external temperature changes, providing more accurate readings. This design also helps to reduce heat loss or gain from the surroundings, improving the thermometer's sensitivity and precision.
How does the cork act as a protective tissue?
The cork is an external, secondary tissue that is impermeable to water and gases. Cork cell walls also contain a chemical called suberin, a waxy substance which protects the stem against water loss, invasion of insects into the stem and prevents infections by bacteria and fungal spores.
