Корень может представлять собой 3 типа частей- главный,придаточный и боковой(см.приложение 1).
Принято различать два распространенных типа корневой системы: Стержневой и Мочковатый(см.приложение 2).
Стержневая корневая система характерна для двудольных(но есть свои исключения,приведу в пример Большой подорожник-у него мочковатая корневая система).Особенностью корневой системы является- мощный,хорошо развитый Главный корень.Образована такая система главным и боковыми корнями.
Представители стержневой системы: клен,цикорий,свекла,морковь,одуванчик.
А Мочковатая корневая система характерна для однодольных.Это система образована боковыми и придаточными корнями,а вот главный корень или плохо развит или совсем отсутствует.
Представители мочковатой системы:овес,ячмень,тюльпан,чеснок,кукуруза

The new girl in your class seems very interesting and you would like to get to know her better. The guy at the skate park does some amazing tricks and you would like him to show you how. But. whenever the opportunity to talk to them comes up, you can't think of anything to say. Your palms sweat, you blush, and you look away.

Whether you are starting a new school, going to a party where you don't know anyone or want to approach a person you fancy, you often need to break the ice in order to start a friendly conversation. Breaking the ice means saying or doing something to stop feeling shy or uncomfortable around someone you don't know very well. The reason you feel this way is that you don't know how the other person will react, but don't let it get you down.

You shouldn't worry. Almost everyone feels uncomfortable when they first meet other people. If you feel this way. the following tips can help you out.

Smile: When you smile, people think you are friendly and easy to talk to. They are also very likely to smile back and help you feel more comfortable about starting a conversation.

Develop passions: The best way to have interesting conversations is to be an interesting person! Get involved in activities and talk about them. Make sure you have something to add to a conversation.

Be positive: Everybody likes to be around happy people. Try to always look on the bright side of life and to see something positive even in negative situations. People will enjoy your positive energy and benefit from it. Also, be confident. If you like yourself, others will probably like you too.

Be a good listener: Develop listening skills. Don't take over the conversation and don't only speak about yourself. Ask other people questions about themselves too. This way they'll know you're interested in them.

Get out there: Don't avoid being around new people just because you feel uncomfortable. If you stay in a situation, you'll get used to it. It's not easy, but it's worth it. After all, the other person may want to talk to you as well -but be too shy to break the ice!
